A La-doped Cu11O2 (VO4)6 photocatalyst with optimum La/Cu molar ratio of 4% was prepared by sol-gel method. XRD,SEM and EDX have been employed to characterize the as-synthesized materials. During liquid phase photocatalytic degradation of MO under the UV-light, the as-prepared La/ Cu11O2 (VO4)6 exhibits higher activity than the pure Cu11O2 (VO4)6. It found that the La/ Cu11O2 (VO4)6 prepared with the La/Cu molar ratio of 4% and calcinated under 500°C for 4 hours was pure triclinic phase. In this conditions, the sample had highest photocatalytic activity with the photodegradation rate was about 92.45% or so in 60min under 20W UV light.
