Photo-oxidation of water sensitised by cadmium sulphide dispersions
Abstract
A dispersion of CdS in alkali (pH > 12) was employed to sensitise the photo-oxidation of water to O2 by a sacrificial electron acceptor, PtCl62–; heat treatment and platinisation of the CdS particles prior to irradiation markedly improved (20–40 times) their sensitising power.
