Novel inorganic perovskite quantum dots for photocatalysis

Abstract

Herein, we report the performance of CsPbX3 (X = Cl, Br, and I) perovskite quantum dots (QDs) for photocatalytic degradation of organic dyes. The photocatalytic performance of CsPbX3 QDs was characterized by UV-vis absorption spectra and ESI-MS, which evaluated their ability of degrading methyl orange (MO) solution under visible light irradiation. Interestingly, both CsPbCl3 and CsPbBr3 QDs show excellent photocatalytic activities, which can decompose the MO solution into a colorless solution within 100 min. This study demonstrates the potential of CsPbX3 QDs in the degradation of organic dyes and environmentally friendly applications. Moreover, the integration of CsPbX3 QDs and photocatalysis provides a new insight for the design of new photocatalysts.
