A novel series of photocatalysts for an overall water splitting is reported. The catalysts have a layered perovskite type structure with a general formula of A{sub 2{minus}x}La{sub 2}Ti{sub 3{minus}x}Nb{sub x}O{sub 10} (A = K, Rb, Cs; x = 0, 0.5, 1.0). The catalysts, except for the one with x = 1.0, are spontaneously hydrated, and the band gap irradiation induced efficient evolution of H{sub 2} and O{sub 2} in a stoichiometric ratio from an aqueous alkaline solution when a proper amount of Ni loading was made. The reaction mechanism of water splitting on these catalysts is discussed on the bases of the structural study of the catalysts.
