Most implementations of the photoanode for water splitting are based on semiconductors and inorganic catalysts, wherein the surface defect and the grain boundary of inorganic materials have been a major barrier hindering the charge transfer between the light absorber and the catalyst. Here we report a new type of photoanode for water splitting, featuring the combination of α-Fe2O3 and molecular Ru catalysts. Fabricated by self-assembly, the semiconductor/molecule interface is not only efficient for the light-induced charge separation but also highly catalytic toward the water oxidation reaction. This work opens a new avenue for improving the efficiency of the solar-to-fuel conversion.
