Abstract

Recent developments in titanium dioxide-based photocatalysts are reviewed concerning developments in the highly dispersed TiO2 photocatalysts prepared on or within zeolites and visible light-responsive TiO2 photocatalysts. Special attention is focused on the application of these catalysts in green chemistry, e.g. solar energy conversion and environmental protection. The unique applications of TiO2 species within zeolites for environmental protection such as reduction of CO2 and H2O and direct decomposition of NOx into N2 and O2 are discussed, focusing on the relationship between the reactivity and local structures of the TiO2 species. The preparation of visible light-responsive TiO2 photocatalysts by applying ion engineering techniques such as ion implantation and an RF magnetron sputtering deposition method is discussed, with emphasis on its unique reactivity for the separate evolution of H2 and O2 from water under sunlight irradiation.
