Abstract
AbstractCsPbX3 (X=Cl, Br, I) nanocrystals (NCs) are considered as one of the most promising photocatalytic materials. Unfortunately, their environmental instability, especially the intrinsic water vulnerability, brought their applications major obstacles in the photosynthetic fields. To improve the stability for photocatalytic water splitting, we for the first time chose conductive polymer, polyaniline (PANI), as the encapsulating material to fabricate CsPbBr3@PANI nanoparticles (NPs) by photo‐polymerization method. After optimizing, the photocatalytic hydrogen production efficiency of CsPbBr3@PANI NPs reached 4.81 mmol/(h ⋅ g) and the catalytic lifetime achieved 120 hours. Our work that achieved the stable CsPbBr3@PANI NPs shed light on potential opportunity for catalytic application of CsPbBr3 NCs.
