In-Fe mixed oxide as an oxygen-evolution photocatalyst for visible-light-driven Z-scheme water splitting

In-Fe mixed oxide showed an activity for photocatalytic water oxidation when VO2+ was used as an electron acceptor. The stoichiometric amount of VO2+ for O2 was detected in the solution. The visible-light-driven Z-scheme stoichiometric water splitting was demonstrated using In-Fe mixed oxide and Ru/SrTiO3:Rh as oxygen and hydrogen evolution photocatalysts.
