Abstract

Solar-driven photocatalytic water splitting offers a sustainable pathway to produce green hydrogen, yet its practical application encounters several challenges including inefficient photocatalysts, sluggish water oxidation, severe reverse reactions and the necessity of separating produced hydrogen and oxygen gases. Herein, we design and develop a photocatalytic system composed of two separate reaction parts: a hydrogen evolution cell containing halide perovskite photocatalysts (MoSe2-loaded CH(NH2)2PbBr3-xIx) and an oxygen evolution cell containing NiFe-layered double hydroxide modified BiVO4 photocatalysts. These components are bridged by a I3−/I− redox couple to facilitate electron transfer, realizing…
