Well-graphitized graphene as photoinduced charge transport channel for improving the photocatalytic activity of AgBr

Herein, we present a facile synthesis of AgBr-well-graphitized graphene (WGG) nanocomposites for the first time. The as-prepared AgBr-WGG nanocomposites exhibit extraordinary photocatalytic properties for the degradation of organic pollutants under visible light irradiation. Compared with bare AgBr particles, the AgBr-WGG hybrids show a 9-fold enhancement of photodegradation rate toward organic pollutants, which can be primarily ascribed to the fact that WGG can act as an excellent photoinduced charge transport channel for greatly enhancing charge separation and transportation.
