ABSTRACT:
Gold, silver or palladium can be deposited by photoredox reaction on semiconductor oxide powders by irradiating a suspension of semiconductor oxide powder in the presence of oxygen, CO.sub.2 or mixtures thereof, of an oxidizable system which protects the semiconductor from photocorrosion, and of a salt or complex of copper, lead, mercury, tin, gold, silver or palladium.
