It is known that TiO2 exhibits good photocatalytic properties which could be used in various commercial applications such as water and air purification or photo-induced biodegradation of microbes. TiO2 occurs in nature in the form of three crystal polymorphs: anatase, brookite and rutile. For photocatalytic applications only anatase and rutile are of interest, however anatase shows greater phot...

uv/tio2 photocatalysis of chelated copper in aqueous solutions has been performed starting from cu(ii)-tartaric acid, cu(ii)-citric acid, cu(ii)-edta and cu(ii)-dtpa,in the presence of oxygen and at acidic ph. the photocatalytic reaction obeys first-order kinetic equation. the influence of cu(ii) on photocatalytic oxidation of organic ligands and how the various organics will affect the treatmen...

in this work, ferric coagulation and acid cracking as olive mill wastewater (omw) pretreatments during photocatalysis process were compared in batch recirculation reactor. as ferric ions influence, ferric coagulation has preference over acid cracking. ferric ions influence on intensification of penolic components absorption on tio2 surfacein initial and oxidize organic pollutant during photocat...

Abstract Semiconductors and the associated methodologies applied to electrochemistry have recently grown as an emerging field in energy materials technologies. For example, semiconductor membranes heterostructure fuel cells are new technological trend, which differ from traditional cell principle employing three basic functional components: anode, electrolyte, cathode. The electrolyte is key de...
