Photocatalytic properties of layered hydrous titanium oxide/CdSZnS nanocomposites incorporating CdSZnS into the interlayer

H\+v\2\-v\Ti\+v\4\-v\O\+v\9\-v\/Cd\+v\0.8\-v\Zn\+v\0.2\-v\S nanocomposites less than 1 nm thick were fabricated by the reaction between a Cd-Zn ions mixture and H\+v\2\-v\S in the interlayer of H\+v\2\-v\Ti\+v\4\-v\O\+v\9\-v\. The nanocomposites were capable of efficient H\+v\2\-v\ evolution following irradiation with light in the presence of Na\+v\2\-v\S, and the H\+v\2\-v\ productivity of the composite was higher than with unsupported sulphides or a mixture of the sulphides and H\+v\2\-v\Ti\+v\4\-v\O\+v\9\-v\. H\+v\2\-v\ production could be enhanced by doping with Pt but not by coating with Pt.
