Photocatalytic Hydrogen Production by Stable CsPbBr3@PANI Nanoparticles in Aqueous Solution

다국어 초록 (Multilingual Abstract)

CsPbX3 (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.
Hydrogen generation: A facile strategy to synthesize nearly monodispersed CsPbBr3@PANI nanoparticles by the photopolymerization method and successfully to show excellent properties of photocatalytic water splitting, holding new prospects for photocatalytic hydrogen production in the near future.
