Abstract

All-inorganic CsPbX ₃ (X = I, Br, Cl) perovskite nanocrystals (NCs) have attracted much attention in clean energy fields such as solar cells and light-emitting diodes due to their excellent opto-electric properties. Herein, we extended the application of perovskite NCs to the photocatalytic degradation field. We demonstrated a facile strategy for highly efficient and feasible synthesis of pure CsPb(Br _1-x Cl _x ) ₃ NCs and CsPb(Br _1-x Cl _x ) ₃ -Au nanoheterostructures. The photocatalytic performance of CsPb(Br _1-x Cl _x ) ₃ -Au for degrading water-insoluble carcinogenic Sudan Red III under visible light irradiation was characterized by UV-vis absorption spectra. CsPb(Br _1-x Cl _x ) ₃ -Au nanoheterostructures showed excellent photocatalytic activities, which can degrade about 71% of Sudan Red III within 6 h. This study provides a new way to use semiconductor perovskite-metal nanoheterostructures in photocatalytic applications.
