Cities are generally inferior to 3 the mad quantum dots/from 3 to 4 ultrathin nanosheets 0/2 pairs of composites: enhanced stability and photocatalytic activity

Metal halide perovskite quantum dots (QDs) have good optoelectronic properties and are a potential photocatalyst material. However, its poor stability and insufficient charge transport efficiency hinder its application in photocatalysis. This work will CsPbBr.3 quantum dots in a two dimensional thin decorative gC.3N.4 nano sheet (UCN), the 0D/2D CsPbBr prepared 3/UCN composite photocatalyst. UCN introduced not only by the passivation CsPbBr3 to increase the surface ligands CsPbBr quantum dot3 Stability of quantum dots, and both a band matching may also facilitate the transfer of charge between the two materials. Thus, CsPbBr prepared 3/UCN heterostructure than mere CsPbBr3 has superior photocatalytic properties of quantum dots and UCN, which is based CsPbX stability and high photocatalytic activity is designed to have 3 provides an effective heterostructure strategy.
