▎ 摘　　要

AgBr nanoparticles supported on graphitic-C3N4-decorated nitrogen-doped graphene intercorrelated ternary superhybrid composites (ACNNG-x) acting as a novel visible-light driven photocatalyst are reported. Because of the fast interfacial charge separation and photoelectrochemical performance, the representative of ACNNG-50 superhybrid structure achieves high efficiency and stable photocatalytic capability for organic contaminant degradation and CO2 reduction.
