Synthesis and Enhanced Photocatalytic Activity of Er3+-doped ZnWO4

doi:10.15541/jim20140574

Abstract

Abstract:

Er³⁺-doped ZnWO4 nanorods with different doping concentrations were synthesized by a hydrothermal method. The as-prepared products were characterized by XRD, TEM and DRS. The photocatalytic activities of the as-prepared ZnWO₄ samples were evaluated by photo-degradation of RhB under simulated solar light irradiation and the effects of Er³⁺ doping on the photocatalytic activity of ZnWO₄ were investigated. The result showed that the sample with the doping concentration of 2mol% exhibited the best photocatalytic performance, which could be ascribed to the promoted charge separation efficiency of Er³⁺-doped ZnWO₄.

Key words: Er³⁺-doped ZnWO₄, photocatalyst, Rhodamine B, charge separation
