研究了Au-25修饰的二氧化钛的可见光驱动光催化性能。它能引起苯酚衍生物和亚铁氰化物的氧化，以及Ag+、Cu2+和溶解氧的还原。热力学上的上行反应，如苯酚的氧化和Cu2+的还原，也是驱动的。即使在860 nm光下也能观察到基于Au-25激发的光催化作用。(C)2010年，爱思唯尔出版。
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.
