Abstract

Abstract : Photocatalytic H2 Evolution In article number 2200172, Kijung Yong and co‐workers present a Pt/g‐C3 N4 /TiO2 /IrO x hollow sphere for photocatalytic water splitting. The two cocatalysts, Pt and IrO x, are spatially separated along the Z‐scheme charge‐transfer pathway within the g‐C3 N4 /TiO2 heterojunction. The synergistic effect of the spatial separation of cocatalysts and the Z‐scheme heterojunction boosts charge separation/transfer, leading to superior and stable photocatalytic H2 evolution in water.
