Visible light-driven photocatalysis of Au-25-modified TiO2 was investigated. It induces oxidation of phenol derivates and ferrocyanide and reduction of Ag+, Cu2+ and dissolved oxygen. Thermodynamically uphill reactions such as oxidation of phenol accompanied by reduction of Cu2+ are also driven. The photocatalysis, which is based on the excitation of Au-25, is observed even under 860 nm light. (C) 2010 Published by Elsevier B.V.
