N-doped Cu11O2 (VO4)6 Photocatalyst Prepared by Sol-gel Method

摘要：

　　The N-doped CH11O2 (VO4)6 photocatalyst was prepared using the sol-gel method.Techniques of X-ray diffraction (XRD),scanning electron microscope (SEM) have been employed to characterize the as-synthesized materials.During liquid phase photocatalytic degradation of Methy lorange(MO) under the UV-light,the as-prepared N-doped Cu11O2 (VO4)6 exhibits higher activity than the pure Cu11O2 (VO4)6 without doped N.It found that the N-doped CuriO2 (VO4)6 prepared with the molar ratio of citric acid to metal inons be 2∶1,N/Cu molar ratio of 12%,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 94.42% or so in 60min under 20W ultraviolet lamp.
