▎ 摘　　要

The h-BN/Ag3PO4 composite photocatalysts were facilely prepared via dispersing Ag3PO4 nanoparticles on the surfaces of graphene-like h-BN nanosheets and the physical property, optical properties, crystalline and morphologic properties were explored by characterized by N-2 adsorption-desorption, XRD, FT-IR, XPS, DRS, FE-SEM, TEM and PL analyses. Under visible light, the h-BN/Ag3PO4 composites exhibit enhanced photocatalytic activity towards the degradation of dye and p-Nitrophenol, which was mainly ascribed to the graphene-like h-BN nanosheets support Ag3PO4 presents the enhanced visible light harvesting ability and the effectual spatial separation of photogenerated charge carriers. Recycling experiments confirmed that h-BN/Ag3PO4 catalysts also possessed superior cycle performance and the high photocatalytic stability was due to the reduction of silver ions was effective inhibited by carrying the photogenerated electrons of Ag3PO4 to the graphene-like h-BN. The quenching process of reactive species indicated that h(+) and center dot O-2(-) play dominant role in the degradation of pollutants. The possible transfer pathway of electrons and visible-light photocatalytic degradation mechanism are also discussed ground on the experimental facts. (C) 2016 Elsevier B.V. All rights reserved.
