This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, environmental concerns and the global energy crisis have become two of our greatest challenges. The main purpose of this dissertation research is to design highly active mesoporous materials that can efficiently catalyze environmental and energy related reactions. Surface properties can be easily tuned by thermal treatment and cation doping, resulting in improved catalytic activities. Synthesis and characterization of the materials, catalytic activities for carbon monoxide oxidation, oxygen reduction and oxygen evolution reactions, and mechanistic studies are covered in this thesis. The first part describes the synthesis of mesoporous cobalt oxides through an inverse micelle route for low temperature carbon monoxide oxidation applications. The prepared material showed much better activity and stability compared with commercial cobalt oxide due to its nanoparticle nature and porous structure. The catalytic performance under both dry and moisture rich conditions were tested. Detailed characterization of the materials suggested that high surface areas and the presence of surface oxygen vacancies were critical for enhanced activities. In real systems, structured catalysts such as monolithic substrates coated with a layer of active material are used instead of powder form catalysts. To evaluate the potential of our catalysts to be used in practical catalytic devices, mesoporous metal oxides (MnOx, Co3O4, CeO2) were coated on cordierite substrate by dip coating and in-situ growth and were used as low temperature diesel oxidation catalysts. The resulting materials showed promising catalytic performance. The effect of particle size, loading amount and Cu doping on the catalytic performance are discussed in detail. In the last part, mesoporous cobalt oxides were used as bifunctional catalysts for oxygen reduction and oxygen evolution reactions. If a catalyst can catalyze both reactions, it will have great potential in the application of rechargeable metal air batteries. Ni and Mn doping were introduced into the cobalt oxide material to increase the conductivity and active site population. The Ni incorporated cobalt oxide exhibited the best activity, which can be considered as a potential substituent for precious metal catalysts (Pt, Ir, Ru). Furthermore, the intrinsic structure-property relationships of the materials were established.

This book was released on 2012 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finding a promising material and constructing a new method to have both high energy and power are key issues for future energy storage systems. This dissertation addresses three different materials systems to resolve those issues. Pseudocapacitive materials such as RuO2 and MnO2 display high capacitance but Nb2O5, displays a different charge storage mechanism, one highly dependent on its crystal phase rather than its surface area. Various sol-gel techniques were used to synthesize the different phases of Nb2O5 and electrochemical testing was used to study their charge storage with some phases displaying comparable charge storage to MnO2. To overcome the electrical limitations of using an insulating material, the core-shell structure (Nb2O5/C) was also examined and the method could be generalized to improve other pseudocapacitors. Besides electronic conductivity, the diffusion of the electrolyte ions through the shell material is a critical factor for fast charging/discharging in the core-shell structure. This dissertation also involves another topic, a reconfigurable electrode, that displays both high energy and power density. By constructing a reconfigurable electrode which has different electrical properties (metallic or insulating state) depending on the amount of intercalated `guest' ions into `host' material, it can be used as a battery or electrochemical capacitor material in the insulating or metallic state respectively. Metal oxide bronzes having metal-insulator transition were investigated in this study.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the recent development of metal oxides, hydroxides and their carbon composites for electrochemical oxidation of water in the production of hydrogen and oxygen as fuels. It includes a detailed discussion on synthesis methodologies for the metal oxides/hydroxides, structural/morphological characterizations, and the key parameters (Tafel plot, Turnover frequency, Faradic efficiency, overpotential, long cycle life etc.) needed to evaluate the electrocatalytic activity of the materials. Additionally, the mechanism behind the electro oxidation process is presented. Readers will find a comprehensive source on the close correlation between metal oxides, hydroxides, composites, and their properties and importance in the generation of hydrogen and oxygen from water. The depletion of fossil fuels from the earth’s crust, and related environmental issues such as climate change, demand that we search for alternative energy resources to achieve some form of sustainable future. In this regard, much scientific research has been devoted to technologies such as solar cells, wind turbines, fuel cells etc. Among them fuel cells attract much attention because of their versatility and efficiency. In fuel cells, different fuels such as hydrogen, CO2, alcohols, acids, methane, oxygen/air, etc. are used as the fuel, and catalysts are employed to produce a chemical reaction for generating electricity. Hence, it is very important to produce these fuels in an efficient, eco-friendly, and cost effective manner. The electrochemical splitting of water is an environmentally friendly process to produce hydrogen (the greener fuel used in fuel cells), but the efficiencies of these hydrogen evolution reactions (cathodic half reaction) are strongly dependent on the anodic half reaction (oxygen evolution reaction), i.e., the better the anodic half, the better will be the cathodic reaction. Further, this oxygen evolution reaction depends on the types of active electrocatalysts used. Though many more synthetic approaches have been explored and different electrocatalysts developed, oxide and hydroxide-based nanomaterials and composites (with graphene, carbon nanotubes etc.) show better performance. This may be due to the availability of more catalytic surface area and electro active centers to carry out the catalysis process.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binary and mixed oxides incorporating transition metal cations host a broad range of scientifically compelling and technologically significant optical, electronic, and magnetic properties. Transition metal oxides (TMOs) are being explored for applications in energy storage, optoelectronics, sensors, and magnetic storage among many other potential uses. The diverse range of physical properties within this class of materials arises from the large flexibility in chemical compositions and crystal structures. These compositions and structures can be generated during synthesis or tailored after synthesis with external stimuli. In this thesis, I develop strategies for reaching structural and chemical states in transition metal oxides with technologically important optical and electronic properties. I demonstrate a new synthesis strategy for single-crystal SrVO3 films - a transparent conducting oxide with potential applications in display and photovoltaic technologies - using solid-phase epitaxy. By this technique, epitaxial layers of SrVO3 are crystallized from amorphous precursor films. The electrical conductivity and visible light transmission in these epilayers are comparable with SrVO3 formed through other epitaxial synthesis methods. This synthesis route employs thin film deposition and crystallization techniques that are scalable to m2 surface areas. Scalability is a crucial step for commercial applications of transparent conducting oxide layers. Crystal growth from amorphous precursor films is a recent development for transition metal oxides that have traditionally been synthesized using vapor-phase epitaxy. As a result, fundamental insight into the amorphous-to-crystalline transformation and defect formation processes in solid-phase epitaxy for transition metal oxides is comparatively rare. In situ synchrotron x-ray characterization is a powerful experimental approach for gathering mechanistic insight for crystal growth processes. I have designed new instrumentation for synchrotron x-ray studies of the amorphous layer deposition, crystallization, and defect formation processes inherent to solid-phase epitaxy. This instrumentation combines a vacuum sample deposition and crystallization environment with x-ray focusing optics for in situ x-ray microbeam diffraction, reflectivity, and scattering studies. Design features and key capabilities are demonstrated through a series of results from experiments performed during the commissioning of the instrument at the Advanced Photon Source. In a separate ex-situ study, I examine the crystal structure of micrometer-scale regions of SrTiO3 crystallized from nanoscale seeds using lateral solid-phase crystallization. Using a high-energy synchrotron x-ray beam focused to 200 nm, I reveal a continuous rotation in the lattice planes in the laterally crystallized regions. A rotation of nearly 25[degrees] per micrometer of lateral crystallization is measured for several SrTiO3 crystals independent of the crystallographic orientation of the growth front. The uniform lattice rotation rate suggests a single defect formation process that is characteristic of lateral crystal growth through an amorphous precursor layer. These findings support a hypothesis that the lattice rotation is driven by dislocations that form in response to mechanical stresses arising from the density difference across the crystal-amorphous interface. Controlling the oxygen environment is crucial to forming specific structural phases during synthesis. Similarly, modifications to oxygen stoichiometry can be used to modify the physical properties in epitaxial thin films of multivalent transition metal oxides. In this project, I use x-ray nanobeam diffraction and scanning near-field optical microscopy to simultaneously probe the structural and optoelectronic features of oxygen-deficient epitaxial monoclinic vanadium dioxide thin-films. In this study, an electrically conductive phase is patterned in insulating vanadium dioxide using intense electric fields delivered from an atomic force microscope probe. Electrical conductivity arises from oxygen vacancies created in the presence of the electric field that modify the electronic band structure. The stability and relaxation of the electrically conducting state are governed by the oxygen vacancy dynamics that can be manipulated with hard x-ray irradiation. This study demonstrates a way to manipulate nanoscale structural and electronic states in vanadium dioxide with local electric fields and focused hard x-rays, bringing new insights into the stability of the oxygen-deficient conductive phase of vanadium dioxide.
