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 TiO
2 act as efficient photocatalysts for the NO decomposition reaction into N
2 and O
2 as well as the H
2 and O
2 evolution reaction from water.
