AgCl/Ag/g-C(3)N(4) Hybrid Composites: Preparation, Visible Light-Driven Photocatalytic Activity and Mechanism

The ternary plasmonic AgCl/Ag/g-C(3)N(4) photocatalysts were successfully fabricated by a modified deposition–precipitation method, through which Ag/AgCl nanoparticles (5–15 nm in size) were evenly dispersed on the surface of g-C(3)N(4). The AgCl/Ag/g-C(3)N(4) composites exhibited higher photocataly...

Descripción
Sumario:The ternary plasmonic AgCl/Ag/g-C(3)N(4) photocatalysts were successfully fabricated by a modified deposition–precipitation method, through which Ag/AgCl nanoparticles (5–15 nm in size) were evenly dispersed on the surface of g-C(3)N(4). The AgCl/Ag/g-C(3)N(4) composites exhibited higher photocatalytic activity than Ag/AgCl and g-C(3)N(4). The enhanced photocatalytic performance could be attributed to an efficient separation of electron–hole pairs through a Z-scheme mechanism, in which Ag nanoparticles acted as charge separation centers.
