Synthesis of Highly Efficient CsPbBr3@Pb-MOF Photocatalyst at the Water-Oil Interface by Ultrasonication

Abstract

In recent years, all inorganic perovskites have proven to be excellent photocatalytic materials. However, its poor stability and severe recombination of photogenerated electrons and holes have hindered its wide application. Herein, we employed a convenient and rapid one-pot sonochemical method to incorporate CsPbBr3 into Pb-MOF, aiming to enhance the stability and efficiency of photogenerated electron transfer. The CsPbBr3@Pb-MOF shows good photocatalytic efficiency, and 70% tetracycline hydrochloride (TCH) water solution is decomposed at 60 min visible light (λ>420 nm) irradiation. Meanwhile, CsPbBr3@Pb-MOF exhibits excellent photocatalytic stability.
