Abstract

High Resolution Image Download MS PowerPoint Slide The introduction of a semiconductor–semiconductor junction is an effective strategy to enhance the photocatalytic performance of perovskite nanocrystal-based systems. Herein, we optimized the synthesis of CsPbX 3 /Pb 4 S 3 Y 2 (X, Y = Cl, Br, I) perovskite/chalcohalide heterostructures, whose band alignment can be tuned by the halide composition. As a proof-of-concept, we evaluated the photooxidative coupling of p -substituted thiophenols at room temperature, under visible light, in air, and without a sacrificial electron donor. Notably, CsPbBr 3 /Pb 4 S 3 Br 2 achieved up to 94% selectivity toward disulfide ( p -OCH 3 thiophenol with a turnover number of 14 300), highlighting the crucial role of the type-II heterojunction in promoting charge separation and efficient electron delocalization across the junction.
