Design and development of second-generation titanium oxide photocatalyst materials operating under visible light irradiation by applying advanced ion-engineering techniques

Advanced ion-beam techniques such as metal ion-implantation, ionized cluster beam (ICB) deposition and RF-magnetron sputtering (RF-MS) deposition were found to enable the development of unique titanium oxide photocatalyst materials which are able to absorb and work not only under UV but also visible or solar light irradiation. Thus prepared visible light-responsive TiO2 act as efficient photocatalysts for the NO decomposition reaction into N2 and O2 as well as the H2 and O2 evolution reaction from water.
