Abstract The photocatalytic conversion of biomass feedstock represents a promising and environmentally friendly strategy for achieving selective transformation value addition. slow charge dynamics sluggish hole transfer in the oxidation reactions severely limit activity. Here, heterojunction is fabricated by synthesizing ultra thin ZnIn 2 S 4 nanoflower with spinel CuCo O . internal interfacial electric fields are successfully constructed, which shows superior 5‐hydroxymethylfurfural (HMF) valorization. HMF undergoes severe mineralization when used as catalyst, resulting 0.9% 2,5‐diformylfuran (DFF) yield water, while /CuCo catalyst exhibits 77% DFF selectivity 88.6% conversion, cascaded bulk greatly reduce potential holes enhance separation efficiency, thus give remarkable 70‐fold increase yield. This work overcomes limitations application similar alcohol that typically require organic solvents, high evolution rate 724.9 µmol·g −1 ·h water within first hour reaction, surpassing most reports oxidation.
