Abstract The formation of light-sensitive electrodes by coating a platinum mesh from an aqueous suspension of a semiconductor, is demonstrated. They behave as short-circuited semiconductor electrodes, and the shortcircuiting can be reduced by incorporation of Teflon in the coating. The photochemistry of some little investigated or uninvestigated semiconductors (metallic oxides, sulphides and chromates) is described; all respond to visible light, all are unstable on irradiation, and only p-type Pb3O4 appears useful as a photocathode. Photoacoustic spectra of some of these materials are presented. The shortcomings, and possible improvements, of this photoelectrode preparation method are discussed.
