Available in PDF, EPUB and Kindle. Book excerpt: The oxygen evolution reaction (OER) is the ideal anodic reaction for a photoelectrochemical cell that converts solar energy into chemical fuels; however it is currently limited by catalyst efficiency and cost. In order to overcome these limitations, much effort has been devoted to the discovery of more efficient earth-abundant metal oxide electrocatalysts, particularly mixed-metals oxides, as well as understanding their mechanisms. This thesis addresses both of these challenges. An O2-sensitive fluorescence-based screening assay was developed and arrays of ternary oxide electrocatalysts were examined. Analysis of the intensity of the resulting fluorescence signal allowed for the identification of compositions with high activity. Compositions exhibiting the highest activities were validated through Tafel analyses, and good qualitative agreement was observed between screening results and electrochemical measurements. While Fe is known to improve the activity of Ni oxide catalysts, the incorporation of a third metal into Ni-Fe binary oxides was often observed to further enhance OER activity, with Ni-Fe-Al amorphous oxide showing the highest activity during our initial screening. The previously observed instability led to the investigation of a well-defined NiFeAlO4 inverse spinel oxide as a water oxidation electrocatalyst, where structural analyses confirmed the substitution of Al for Fe lattice sites. A comparison of electrochemical activity against compositionally and structurally relevant oxides, including the known OER catalysts NiO, NiFe 9:1, and NiFe2O4 established NiFeAlO4 as a superior electrocatalyst with no Al leaching, and cyclic voltammograms of the oxides indicated that the electron-withdrawing M+3 ions in the inverse spinels make Ni+2 sites more difficult to oxidize. Furthermore, it was observed that neither of the bimetallic spinel oxides (NiFe2O4 & NiAl2O4) outperformed NiFeAlO4, suggesting a unique synergistic effect between all three metal sites that influences the OER rate determining step. In addition to catalyst discovery, we also pursued mechanistic studies to better understand the dramatic activity enhancement that results when Fe is added to various Ni oxide electrocatalysts. Operando Mössbaurer spectroscopic studies of a 3:1 Ni:Fe layered oxide and anhydrous Fe oxide electrocatalyst was performed. Catalyst materials were prepared by a hydrothermal precipitation method that enabled growth of the oxide catalysts directly on a carbon paper electrode, thereby enhancing charge transport and mechanical stability needed for the operando studies. Fe+4 species are evident in the NiFe-oxide catalyst during steady-state water oxidation, accounting for up to 21% of the total Fe in the catalyst. No Fe+4 is detected under any conditions in the Fe-oxide catalyst. The lifetime of the observed Fe+4 species suggests they do not participate directly in water oxidation; however, their presence has important implications for the promoting effect of Fe in NiFe-oxide electrocatalysts.

This book was released on 2020-05-14 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The occurrence of available energy reservoirs is decreasing steeply, therefore we are looking for an alternative and sustainable renewable energy resources. Among them, hydrogen is considered as green fuel with a high density of energy. In nature, hydrogen is not found in a free state and it is most likely present in the compound form for example H2O. Water covers almost 75% of the earth planet. To produce hydrogen from water, it requires an efficient catalyst. For this purpose, noble materials such as Pt, Ir, and Ru are efficient materials for water splitting. These precious catalysts are rare in nature, very costly, and are restricted from largescale applications. Therefore, search for a new earth-abundant and nonprecious materials is a hot spot area in the research today. Among the materials, nanomaterials are excellent candidates because of their potential properties for extended applications, particularly in energy systems. The fabrication of nanostructured materials with high specific surface area, fast charge transport, rich catalytic sites, and huge ion transport is the key challenge for turning nonprecious materials into precious catalytic materials. In this thesis, we have investigated nonprecious nanostructured materials and they are found to be efficient for electrochemical water splitting. These nanostructured materials include MoS2-TiO2, MoS2, TiO2, MoSx@NiO, NiO, nickeliron layered double hydroxide (NiFeLDH)/Co3O4, NiFeLDH, Co3O4, Cu-doped MoS2, Co3O4- CuO, CuO, etc. The composition, morphology, crystalline structure, and phase purities are investigated by a wide range of analytical instruments such as XPS, SEM, HRTEM, and XRD. The production of hydrogen/oxygen from water is obtained either in the acidic or alkaline media. Based on the functional characterization we believe that these newly produced nanostructured materials can be capitalized for the development of water splitting, batteries, and other energy-related devices.

Download or read book Developing Enhanced Mixed Metal Oxide Catalysts for Electrocatalytic Water Oxidation Using Insights from X ray Absorption Spectroscopy written by Linsey C. Seitz and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient and economic conversion of renewable energy sources is critical for development of technologies that can shift global energy dependence away from fossil fuels. Increased global energy consumption along with heightened awareness of environmental, health, and political issues with fossil fuels are driving the need for alternative technologies. Wind and sun provide more than enough energy to meet the growing energy demand, provided that challenges with intermittency, scale, and cost-effectiveness can be overcome. These obstacles can be mitigated through development of highly active catalysts using abundant and inexpensive materials to convert solar and wind energy into fuels and chemicals. One promising method of converting solar energy into fuel is by splitting water to produce hydrogen and oxygen. This can be achieved using a monolithic photoelectrochemical (PEC) water splitting device which combines photon-absorbing semiconductors with catalysts that drive the respective reactions or a photovoltaic/electrolyzer system which separates these two components. The first part of this thesis presents a model to quantify loss mechanisms in PEC water splitting based on the current state of materials research and calculate maximum solar-to-hydrogen (STH) conversion efficiencies. Results of this model indicate that a major limitation to the efficiency of solar-driven electrochemical water splitting is the oxygen evolution reaction (OER) which requires significant overpotential beyond the thermodynamic redox potential to proceed. The remainder of this dissertation focuses on understanding the interaction between metals in mixed metal oxide catalysts for the OER using electrochemical and advanced spectroscopic techniques towards the development of highly active and stable catalysts. Mixed metal oxide catalysts provide a robust platform for tuning binding energies of OER reaction intermediates to the catalyst surface, thereby affecting activity, through controlled material composition and geometry. We investigate two distinct mixed metal oxide catalyst systems using X-ray absorption spectroscopy (XAS) to probe local geometric and electronic structure and correlate the results with changes in activity. XAS is a synchrotron based technique which provides elemental-specific information by exciting electronic transitions from core to valence orbitals at various elemental edges. XAS studies at the Co K and L edges for a cobalt titanium oxide (CoTiOx) catalyst system identify stabilization effects on the Co oxidation state and overall structure from varying amounts of Ti precursor used during material synthesis. XAS before and after catalyst exposure to OER conditions indicate that catalysts with the least long range order become most oxidized and exhibit the highest activities. Similarly, in situ XAS at the Mn K and Au LIII edges reveal that there is a charge transfer at interfacial sites between manganese oxide (MnOx) and gold (Au) under OER conditions which coincides with significantly increased OER activity compared to MnOx without Au. Our results indicate that Au facilitates stabilization of more oxidized phases of Mn at lower overpotentials, thereby allowing for earlier onset of OER and higher activity. Lastly, we present an investigation of a novel mixed metal oxide catalyst, strontium iridium oxide (SrIrO3) which has the highest reported activity for any known OER catalyst. While it depends on use of Ir, a precious metal, its remarkably high activity compared to rutile IrO2 reduces the Ir loading necessary to achieve similar current densities. In summary, this dissertation explores a broad spectrum of catalysts for the oxygen evolution reaction and uses advanced material characterization methods to draw correlations between the structure, oxidation state, and catalytic activity for these materials. This work provides fundamental insight towards improving efficiency of electrochemical water oxidation processes for the conversion of renewable energy sources to fuels and chemicals.

This book was released on 2015 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of catalysts with earth-abundant elements for efficient oxygen evolution reactions is of paramount significance for clean and sustainable energy storage and conversion devices. Our group demonstrated recently that the electrochemical tuning of catalysts via lithium insertion and extraction has emerged as a powerful approach to improve catalytic activity. Here we report a novel in situ electrochemical oxidation tuning approach to develop a series of binary, ternary, and quaternary transition metal (e.g., Co, Ni, Fe) oxides from their corresponding sulfides as highly active catalysts for much enhanced water oxidation. The electrochemically tuned cobalt-nickel-iron oxides grown directly on the three-dimensional carbon fiber electrodes exhibit a low overpotential of 232 mV at current density of 10 mA cm-2, small Tafel slope of 37.6 mV dec-1, and exceptional long-term stability of electrolysis for over 100 h in 1 M KOH alkaline medium, superior to most non-noble oxygen evolution catalysts reported so far. The materials evolution associated with the electrochemical oxidation tuning is systematically investigated by various characterizations, manifesting that the improved activities are attributed to the significant grain size reduction and increase of surface area and electroactive sites. This work provides a promising strategy to develop electrocatalysts for large-scale water-splitting systems and many other applications.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Metal oxide catalysts for alkaline water electrolysis were created through cathodic electrodeposition and the deposition variables were explored. It was discovered that the use of ammonium electrolytes and higher current densities during deposition improved catalytic kinetic performance for the oxygen and hydrogen evolution reactions. A NiFe oxide catalyst was developed with a greater than 99 % ideal charge transfer coefficient for oxygen evolution and a NiV oxide catalyst was developed with a greater than 99.9 % ideal charge transfer coefficient. Combined, the NiFe and NiV catalysts catalyzed water electrolysis at greater than 99 % efficiency below 10 mA/cm^2. The NiFe oxide was characterized as being both highly conductive and highly disordered. NiFe, CoFe, and NiCo oxide oxygen evolution catalytic mechanisms were elucidated with electrochemical impedance spectroscopy. The relationship between the charge transfer coefficient of the Butler-Volmer model and the charge transfer resistance of electrochemical impedance spectroscopy was empirically demonstrated. The distortions of impedance on non-linear systems was demonstrated and discussed.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical alcohol oxidation has received increasing attention due to its advantages of being environmentally benign and proceeding efficiently without the use of stoichiometric amounts of chemical oxidizing agents. In recent years, a number of homogeneous and heterogeneous catalysts have been developed for electrochemical alcohol oxidation, many with an emphasis on the electrochemical oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA). The use of the nitroxyl radical 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) as an electron mediator has been shown to be an effective catalyst for achieving efficient electrochemical alcohol oxidation in mildly alkaline conditions. In a similar manner, a variety of Ni- and Co containing metal oxide-based heterogeneous catalysts have been shown to achieve high catalytic activities for electrochemical alcohol oxidation under more basic conditions. While the efficacy of these catalysts are well-established, insights into their intrinsic catalytic properties and the factors that affect their overall performance for electrochemical alcohol oxidation are lacking. The work herein outlines various studies in which the catalytic properties of nitroxyl radicals and metal oxide-based catalysts were carefully investigated. By systematically varying the reaction conditions for electrochemical alcohol oxidation, novel insights into the oxidation mechanisms and specific regeneration pathways that are active during electrochemical alcohol oxidation were obtained. The insights provided here contribute to the comprehensive understanding of the factors that affect the overall catalytic activity of nitroxyl radicals and metal oxide based catalysts for electrochemical alcohol oxidation.
