Single-Atom Ru in CoFe-LDH Drives Efficient Charge Separation on BiVO₄ for Solar Water Splitting.

ABSTRACT: Bismuth vanadate (BiVO₄) is regarded as a promising photoanode for photoelectrochemical (PEC) water splitting. Despite its advantage in band gap and visible-light response, the BiVO₄ exhibits an unsatisfactory achieving water splitting due to severe charge recombination. Herein, we elucidate an innovative approach involving the incorporation of single Ru atom with a CoFe-LDH cocatalyst (Ru_0.51-CoFe-LDH) and integrating it onto the BiVO₄ semiconductor substrate. The resulting Ru_0.51-CoFe-LDH/BiVO₄ photoanode film demonstrates commendable charge injection efficiency (76%) and charge collection efficiency (100%). Interestingly, the yield of hydrogen and oxygen increases linearly at a stoichiometric ratio of about 2:1, reaching
