CsPbBr3 Perovskite Quantum Dots/Ultrathin C3N4 Nanosheet 0D/2D Composite: Enhanced Stability and Photocatalytic Activity
Source abstract
Abstract
Metal-halide perovskite quantum dots (QDs) have emerged as a potential photocatalyst owing to their remarkable optoelectronic properties. However, the poor stability and insufficient charge transportation efficiency of this type of materials hindered their applications in the photocatalysis field. Herein, we decorated CsPbBr 3 QDs on two-dimensional (2D) ultrathin g-C 3 N 4 (UCN) nanosheets to develop a 0D/2D CsPbBr 3 /UCN composite photocatalyst. The introduction of UCN can not only improve the stability of CsPbBr 3 QDs by passivating the surface ligands of CsPbBr 3 QDs, but also facilitate the charge transfer due to the suited band gap alignment.
