Download or read book Earth abundant Transition Metal Chalcogenide Electrocatalysts for Renewable Energy Applications written by and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy sustainability is perhaps the greatest ongoing challenge facing humanity. Our need to replace fossil fuel-based sources of energy with environmentally friendly, secure, and renewable alternatives continues to grow, and although this fact has been long realized by the scientific community and beyond, no present-day solution effectively competes with fossil fuels from an economic or performance standpoint. Although several renewable energy technologies, including photovoltaic solar cells and fuel cell systems, can efficiently supply usable power with little or no environmental impact, they often suffer from high costs due to the expensive raw materials and complex processing steps required to produce high performance devices. These costs ultimately limit the scalability of such technologies and, consequently, their potential to address our looming energy concerns. However, the viability of many renewable energy technologies---particularly those rooted in electrochemistry---could be substantially increased by replacing expensive and scarce materials (such as noble metals) with low-cost, earth-abundant alternatives that exhibit comparable performance. The work collected here primarily focuses on identifying and developing such alternative electrocatalysts, generally within the family of transition metal chalcogenides, and assessing their utility in electrochemical energy conversion applications. Chapter 1 reviews both electrochemical energy conversion and alternative earth-abundant electrocatalyst materials, motivating their investigation and outlining the key challenges yet to be overcome. In Chapter 2, metallic cobalt pyrite (cobalt disulfide, CoS2) is introduced as a new earth-abundant electrocatalyst candidate material capable of boosting the performance of quantum dot-sensitized solar cells while simultaneously eliminating their reliance on precious platinum-based electrodes. Chapter 3 further builds upon Chapter 2 by establishing the high intrinsic electrocatalytic activity of CoS2 toward the hydrogen evolution reaction. Here, micro- and nanostructuring strategies are also demonstrated to synergistically enhance the electrocatalytic performance and stability of CoS2. Chapter 4 broadens the family of pyrite-phase electrocatalysts by showing that other earth-abundant transition metal disulfides exhibit electrocatalytic activity toward both polysulfide reduction and the hydrogen evolution reaction. Collectively, this work represents substantial progress toward the development of earth-abundant transition metal chalcogenide electrocatalysts for renewable energy applications, with the expectation that the lessons learned here should translate to other materials systems.

This book was released on 2020 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Generation of hydrogen and oxygen through catalyst-aided water splitting which has immense applications in metal air batteries, PEM fuel cells and solar to fuel energy production, has been one of the critical topics in recent times. The state of art oxygen evolution reaction (OER), oxygen reduction reaction (ORR), hydrogen evolution reaction (HER) catalysts are mostly comprised of precious metals. The current challenge lies in replacing these precious metal-based catalysts with non-precious earth-abundant materials without compromising catalytic efficiency. This research explores mixed metal selenides containing Fe-Ni, Fe-Co and RhSe which were hydrothermally synthesized and/or electrodeposited and tested for OER and ORR catalytic activity in alkaline medium. This spinel class of compounds generically referred to as AB2Se4 where A and B are divalent and trivalent cations respectively. Interestingly, FeCo2Se4 and FeNi2Se4, both showed highly efficient catalytic activity with low overpotential. Increase in performance was observed when these two spinel compositions were mixed with conducting carbon matrix, which decreased the overpotential significantly and increased the stability. Finally, the metal selenides were also applied towards electrochemical bio sensing of dopamine and glucose. Electrodeposited and hydrothermally synthesized CuSe was studied towards detection of ultralow concentrations of dopamine in neutral phosphate buffer solution. The electrodeposited CuSe was also active towards detection of glucose in alkaline electrolyte. CuSe showed low detection limit, high sensitivity and selectivity towards these biomolecules"--Abstract, page v.

This book was released on 2018-04-07 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the design and synthesis of novel one-dimensional colloidal chalcogenide hetero-nanostructures for enhancing solar energy conversion applications. Semiconducting nanomaterials are particular attractive for energy conversion due to the quantum confinement effects dictating their unique optical and electronic properties. Steering the photo-induced charge-flow based on unique bandgap alignment in semiconductor heterojunctions is critical for photo-electric/chemical conversion. The author presents the controllable preparation strategies to synthesize 1D chalcogenide hetero-nanostructures with various fine structures, further been used as excellent template materials for preparing other novel and complex hybrid architectures through a series of chemical transformations. The heterogeneous growth mechanisms of novel hetero-nanostructures is studied for developing a facile and general method to prepare more novel heterostructures. The band gap structure simulations, detailed charge carrier behaviour and unique solar energy conversion properties of the prepared hybrid nanostructures are deeply investigated. This work would open a new door to rationally designing hybrid systems for photo-induced applications.

Download or read book The Synthesis and Characterization of Metal Chalcogenide pedot written by Kimberly L. Anderson and published by . This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the synthesis and characterization of metal chalcogenide/PEDOT:PSS polymer composites as possible thermoelectric materials for thermal energy conversion; specifically, Te, Bi2Te3, Bi2S3, and Ag2Te. The inorganic materials have high Seebeck coefficients while the PEDOT:PSS has high electrical conductivity. This approach allows for optimization of electrical conductivity of the PEDOT while still maintaining the high Seebeck coefficient of the inorganic materials. XRD analysis confirms the crystallinity of the Te, Bi2S3, and Ag2Te synthesized in the presence of PEDOT:PSS. A detailed spectroscopy study revealed several key findings, which may explain the enhanced electrical conductivity seen in Te/PEDOT:PSS composites. XPS revealed loss of the insulating PSS during the purification process but no loss of the conducting PEDOT. XPS also showed the role the polymer plays as a passivating agent as there was minimal oxidation of the nanowires. UV-Vis/NIR and Raman spectroscopy indicated the remaining PEDOT segments on the polymer to be partially reduced with a benzoid-like conformation. Transport measurements showed ohmic and linear I/V curves at room temperature for all films. The temperature dependent electrical conductivity for all systems was measured from 80 - 300 K and Mott's VRH model was used to qualitatively determine the hopping mechanism. All systems are consistent with three dimensional VRH. The temperature dependent measurements also showed that these systems were all thermally activated.
