Dual-functional CoAl layered double hydroxide decorated α-Fe₂O₃ as an efficient and stable photoanode for photoelectrochemical water oxidation in neutral electrolyte

Abstract

An α-Fe₂O₃ photoanode was decorated with a dual-functional CoAl layered double hydroxide for photoelectrochemical water oxidation. The composite photoanode exhibits high efficiency and excellent stability in neutral electrolyte.
