Abstract
Photocatalytic H2 Evolution In article number 2200172, Kijung Yong and co-workers present a Pt/g-C3N4/TiO2/IrOx hollow sphere for photocatalytic water splitting. The two cocatalysts, Pt and IrOx, are spatially separated along the Z-scheme charge-transfer pathway within the g-C3N4/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.
