Overall water splitting on tungsten-based photocatalysts with defect pyrochlore structure
Defect pyrochlore-type oxides, AMWO(6) (A = Rb, Cs; M = Nb, Ta), loaded with nickel oxide showed photocatalytic activity for overall water splitting under ultraviolet-light irradiation. The conduction bands of the materials are thought to be composed of the W5d orbital hybridized with the Nb5d or Ta4d orbital.
