Hydrogen Reduced Rutile Titanium Dioxide Photocatalyst
For TiO2 photocatalysts, recombination of photoexcited electrons and holes would occur in crystalline defects such as oxygen vacancies, Ti ions, and surface states. Therefore, it is believed that the density of crystalline defects should be decreased to improve the photocatalytic activity of TiO2 particles. Contrary to this common knowledge, the introduction of crystalline defects by hydrogen r...
متن کاملVisible-light Photocatalyst - Nitrogen-doped Titanium Dioxide -
A new photocatalyst, known as nitrogen-doped TiO2 (TiO2-xNx), yielding high reactivity under visible light irradiation, together with high potential for mass-productivity, has been developed by using a highly time-efficient development technique that combines computational materials design with experimental syntheses. Under visible light irradiation, TiO2-xNx films and powders exhibit significa...
متن کاملComplete hydrogen release from aqueous ammonia-borane over a platinum-loaded titanium dioxide photocatalyst.
Complete H2 release from ammonia-borane (NH3BH3, AB) in water was achieved by using platinum-loaded TiO2 (Pt/TiO2) via two consecutive reaction steps, i.e., hydrolysis of AB and photocatalytic decomposition of thus formed NH3 in water, under inert conditions at 298 K.
متن کاملOscillation in the Concentration of H2O2 during Advanced Oxidation Processes:TiO2Mediated Sonocatalytic Degradation of Phenol
Sono, photo and sonophotocatalysis are major Advanced Oxidation Processes (AOP) under intensive investigation as potential technologies for the removal of trace pollutants from water.The techniques involve the formation and participation of Reactive Oxygen Species (ROS) like . OH, HO2 . , O2 . , H2O2 etc. Among these, H2O2 is the most stable and is also a precursor for the reactive free radical...
متن کاملPhenol Photocatalytic Degradation by Advanced Oxidation Process under Ultraviolet Radiation Using Titanium Dioxide
BACKGROUND The main objective of this study was to examine the photocatalytic degradation of phenol from laboratory samples and petrochemical industries wastewater under UV radiation by using nanoparticles of titanium dioxide coated on the inner and outer quartz glass tubes. METHOD The first stage of this study was conducted to stabilize the titanium dioxide nanoparticles in anatase crystal p...
