Abstract

Electrodes of La₅Ti₂MS₅O₇ (M = Ag, Cu) were prepared and photoelectrochemical properties of the electrodes were investigated. Two types of electrode preparation methods were carried out: one was spreading a viscous slurry of the bulk powder on a glass plate coated with fluorine-doped tin oxide, and another was thin film growth by vacuum processes followed by annealing treatment. By the use of vacuum processes, clear and higher photocurrent under visible-light irradiation was observed for both La₅Ti₂CuS₅O₇ and La ₅Ti₂AgS₅O₇. The observed photocurrent was photocathodic, indicating that these materials acted as a p-type semiconductor. La₅Ti₂MS₅O₇ are promising materials of a photoelectrode for water splitting under visible-light irradiation.
