Abstract

Doped with up to 70 different metal salts, three semiconductor oxides (TiO₂, SnO₂, and WO₃) formed the basis of three libraries of mixed oxides. From a high-throughput method, over 30 oxides were found to have activities similar to the well-studied Pt-doped TiO₂ towards the catalyzed decomposition of a model pollutant 4-chlorophenol in water on irradiation with visible light. Two of the new materials (Ir-doped WO₃ and Ce-doped SnO₂) have been reproduced by conventional synthesis, and their catalytic activity was confirmed.
