Abstract
A semiconductor photoelectrode resistant to photocorrosion and a method of preparing such a photoelectrode are disclosed. The photoelectrode includes a doped oxide layer on which illumination falls for photo-stimulation. The oxide layer is doped with metallic ions, such as tantalum ions, to suppress photocorrosion. In one oxide doping method, tantalum pentachloride vapor generated by sublimation is directed against a silicon dioxide layer on a heated photoelectrode.
