Effects of Nd Doping on the Photocatalytic Behavior of Cu11O2 (VO4)6

摘要：

　　Nd-doped Cu11O2 (VO4)6 photocatalyst was synthesized by complexing Sol-gel method and characterized by X-ray diffraction (XRD),scanning electron microscope (SEM) and energy Dispersive X-Ray Spectroscopy(EDX).The photocatalytic activity of Nd-doped Cu11O2 (VO4)6 was evaluated by photocatalytic degradation of methyl orange (MO) solution under UV-light.It revealed that the Nd-doped Cu11O2 (VO4)6 prepared with the molar ratio of citric acid to metal inons be 2∶1,Nd/Cu molar ratio of 2%,pH=7 and calcinated under 500℃ for 4 hours was pure triclinic phase.In this conditions,the sample had highest photocatalytic activity with the photodegradation rate was about 95.73% or so in 60min under 20W ultraviolet lamp.
