Z-scheme heterojunctions have emerged as a novel type of environmental and energy photocatalysts owing to their unique charge separation transfer pathways well robust redox capabilities. Herein, this paper reports straightforward technique for fabricating an anisotropic all-solid-state CsPbBr3/Au/g-C3N4 heterojunction, wherein CsPbBr3, g-C3N4, the electron-transfer system (Au) are spatially immobilized. This three-component presented high photocatalytic activity oxidation C-H bonds carboxylic acids, ketones, alcohols, respectively. Notably, metallic Au species, functioning solid-state electron mediators, can significantly accelerate rate photogenerated electrons holes between photocatalysts. As verified by trapping experiments paramagnetic resonance, results indicate that h+ ·O2- serve primary active species in process. study provides perspectives on development high-performance perovskite-based field organic synthesis.
