The strategic design of nanocomposites and their rationally constructed heterojunctions offer an effective approach for enhancing light harvesting optimizing energy conversions. Herein, we report the synthesis aqueous-stable, lead-free Cs3Bi2Cl3Br6 perovskite integrated with g-C3N4. An excellent band alignment Cs–Bi-based g-C3N4 was achieved by tuning anion in perovskite, leading to remarkable photocatalytic performance. construction a hybrid nanocomposite thin film device impressive hydrogen generation rate 341 μmol h–1 g–1, which is 16 times higher than that perovskite@g-C3N4 powder form. test results are albeit when quartz reactor used, where 20 mg optimized catalyst reaches up 539 g–1 apparent quantum efficiency (AQE) 1.32%. Spectroscopic studies, including photoluminescence (PL) time-correlated single photon counting (TCSPC), have established presence long-lived charge-separated state confirmed excited electron injection into Cs3Bi2Cl3Br6@g-C3N4 not only accelerate charge transfer but also significantly enhance evolution stability photocatalysts.
