摘要：

Photoelectrolysis of water with doped TiO2 and SrTiO3 electrodes is reported. Dopants used are transition metals V, Cr, Mn, Fe, Co, Ni, as well as Al. The response to visible light is greatest at Cr, then decreases across this period of elements, being absent in Co, Ni and Al. Hydrogen and oxygen generation are observed with Cr-doped TiO2 under visible light excitation. Ultraviolet light response decreases with the dopants in reverse order, being highest for Al and lowest for V. An explanation is given in terms of the minority carrier diffusion length,1which is calculated for samples with each of the dopants. © 1979.
