Published: Jan. 10, 2025

Abstract Effective photogenerated charge transfer and utilization have been regarded as a critical factor for achieving highly efficient photosynthesis of ammonia. However, the lacks necessary driving force in many catalysts limit directly transfer. In this work, Cu porphyrin‐based monoatomic layer (PML‐Cu) is modified on face‐centered cubic structured defective CdIn 2 S 4 via solvothermal reaction, with strong coupled interfacial Cu─S bond constructed. Owing to formation axial CuS 1 N polarization site, local asymmetric configuration can be created between PML‐Cu form potential difference, inducing rapid transport from bond. Meantime, electron‐enriched site beneficial stabilization * NHOH intermediate state, then lowering NHO→ rate‐limiting step energy barrier. Benefiting these features, PML‐Cu/CdIn exhibit good NH 3 generation rate 1979.0 µmol g −1 h , apparent quantum efficiency 8.56% at 380 nm 7.40% 450 nm, respectively. This work provides an accessible pathway designing coupling boost photocatalysis.
