Sol-gel Modified TiO2 Powder Composite Films for Photoelectrochemical Hydrogen Generation
Abstract Sol-gel modified TiO2 powder composite films were prepared as photoeletrode for the hydrogen generation in a two-compartment photoelectrochemical cell. Commercial Degussa P25 TiO2 powders have been successfully incorporated into TiO2 sol prepared by sol-gel method using tetrabutyl orthotitanate as precursor material to form thick TiO2 films via coating on the indium-tin oxide (ITO) conductive glass. With assistance of polyethylene glycol (PEG), the macroporous structure TiO2 film was obtained after calcination. The film samples were characterized by XRD, SEM and UV-Vis spectrophotometer. The XRD result indicated that TiO2 films were composed of the anatase-rutile mischcrystal phase. Furthermore, the coating layer had a great effect on the photoelectrochemical properties and photocatalytic activity. The experimental results showed that TiO2-P25/ITO film with 5 coating layers demonstrated a maximum hydrogen production rate, which implied that TiO2-P25/ITO film prepared by this convenient and economic method is a promising photocatalyst for efficient hydrogen production.
期刊介绍:
The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
