Dual-channel synthesis of H2O2via photoelectrocatalytic water oxidation and oxygen reduction over a TaON/Ta3N5/CuI/Cu foam electrode

A novel type-II heterojunction TaON/Ta 3 N 5 /CuI powder is loaded on the surface of the Cu foam by electrophoresis assisted one-step calcination, which is used for the synthesis of H 2 O 2 by photoelectrocatalysis (PEC).
