Constructing vacancy-decorated heterojunction photocatalysts is a feasible strategy for highly efficient photooxidation of toluene to benzaldehyde. However, poor interface interaction and vacancy-triggered mismatched redox kinetics seriously impede photocatalytic activity improvement. Herein, chemically bonded Cs3Bi2Br9–x@AgBr core–shell with unified adsorption-redox sites fabricated via an in-situ light-assisted Ag+ insertion method. Experiments theoretical calculations demonstrate that the type-II band alignment interfacial Bi–Br–Ag bonds boosts charge separation. Moreover, because greater oxygen adsorption energy steric-hindrance effect AgBr shell, preferred site O2 modulated from Br vacancy (VBr, trapping holes) its corresponding reduction (AgBr, gathering electrons), thereby ensuring VBr-enhancing adsorption/oxidation on Cs3Bi2Br9. Therefore, exhibits improved benzaldehyde production rate 5.61 mmol g–1 h–1 (selectivity: 91%), outperforming pure Cs3Bi2Br9 by factor 6. This work underlines importance rational design heterointerface at atomic level in photocatalysis.

Light-to-heat conversion represents one of the most promising pathways to utilize full-spectrum solar energy. The key for boosting photothermal in semiconductor-based light absorbers relies on narrowing bandgap harvesting wide-range sunlight and localizing thermal energy via decreasing heat loss. Here, we demonstrate first example using a halide perovskite, Cs4CuSb2Cl12, as material efficient solar-to-heat conversion, with an intrinsic narrow ultralow conductivity. Full-spectrum (200–2500 nm) absorption solar-thermal efficiency up 93.4% are achieved. property enables low-temperature rapid hydrogen production from ammonia borane, 2.0 equiv released, activation 12.2% is realized, without any extra input. This high performance not only provides potential energy-efficient on-board supply fuel cells but also opens new field perovskites utilized convertors.
