This book was released on 2010. Solar Hydrogen Production by Photo-oxidation of Water from Doped Iron Oxide Photoanodes available in PDF, EPUB and Kindle. Hematite thin film electrodes synthesized as photoanodes for the photoelectrochemical hydrogen production from water. A novel electrochemical method in which the iron oxide precursors is co-deposited with diverse metals to create electrochemically doped thin films has been studies. The most promising dopant metals that found have been Pt, Mo, Cr, Ti and Al; which are substituted into the hematite structure in 1-8 % atomic. The films were characterized by scanning electron microscopy, X-ray diffraction, UV-Vis optical spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy to determine the effect of the dopants on the hematite structure and the photoelectrochemical performance as compared to the undoped material. The IPCE (incident photon-to-current efficiency) values of the transition metal doped iron oxide were up to 4 times higher than the undoped samples. Further improvements to the photocatalytic performance were achieved by deposition of oxygen evolution catalysts, as well as modifications to the surface of the hematite photoelectrode.

Download and read online ebook Metal Oxides/Chalcogenides and Composites write by Aneeya Kumar Samantara. This book was released on 2019-08-09. Metal Oxides/Chalcogenides and Composites available in PDF, EPUB and Kindle. 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.
