Abstract:
Ce/ZnO photocatalytic nanomaterials were prepared by constructing Ce4+-doped zeolite imidazolate skeleton materials ZIF-8 with MOFs structure through hydrothermal method and then high-temperature pyrolysis. The structures of the obtained samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),energy disperse spectroscopy(EDS)and specific surface area determination(BET). Using RhB dye as the degradation object,the effects of Ce-doping amounts and calcining temperature on the structure morphology and photocatalytic performance of Ce/ZnO was investigated. The experimental results showed that the photocatalytic activity and stability of Ce/ZnO with uniform particle size and better dispersion,smaller particle size and bigger specific surface area,was improved significantly after Ce-doping while too high calcination temperature could cause the photocatalytic performance to be reduced. When the Ce-doping amount is 2%wt and calcination temperature is 600 ℃,the Ce/ZnO with best photocatalytic performance can degrade RhB more than 99% through 1 h lighting and the degradation rate is still up to 97.89% after four cyclic catalysis.
