Synergetic effect of heterojunction and doping of silver on ZnNb2O6 for superior visible-light photocatalytic activity and recyclability

Ag/ZnNb2O6 heterojunctions with dual roles of silver, including doping of Ag ions into ZnNb2O6 matrix and Ag nanoparticles deposited on ZnNb2O6 surface, showed abnormal visible-light degradation ability of dyes.358
