Abstract

Photocatalytic activity and spectroscopic properties of ZnS suspensions for the two-electron reduction of aldehydes or related compounds in aqueous medium are described. The ZnS suspension (ZnS-0) prepared by cooling from aqueous ZnSOl and Na2S solutions catalyzes photoredox reactions of acetaldehyde, giving ethanol without much H2 evolution as a two- electron-reduction product, and acetic acid, biacetyl, and acetoin as oxidation products. ...
