A g-C3N4 supported graphene oxide/Ag3PO4 composite with remarkably enhanced photocatalytic activity under visible light.

In this work, a ternary composite photocatalyst of graphitic carbon nitride ( g -C 3 N 4 ), graphene oxide (GO), and Ag 3 PO 4 was prepared through a simple precipitation route, in which Ag 3 PO 4 nanoparticles covered or wrapped with GO sheets are supported on g -C 3 N 4 sheets. The composite photocatalyst displays enhanced absorption in the visible region, and exhibited superior photocatalytic activity compared with single-component or binary composite photocatalysts in the photocatalytic decomposition of Rhodamine B. The enhancement of photocatalytic activity could be attributed to the synergistic effect among them. The ternary composite also exhibited enhanced stability, but further efforts should be made to make it more stable. [ABSTRACT FROM AUTHOR]
