Copper oxide/zinc oxide/3A molecular sieve (CuO/ZnO/3A) photocatalyst was prepared by impregnation method and calcined in 450℃,and the structure of Cu O/Zn O/3A was characterized by X-ray diffraction (XRD),UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS),and X-ray photoelectron spectroscopy (XPS).Its photocatalytic denitrification behavior was studied by pyridine-n-octane system for simulated oil source of nitrogen under visible light irradiation.The influences of the preparation conditions of the photocatalyst,the amount of photocatalyst and the time of light irradiation on the photocatalytic denitrification performance were investigated.With the increase of the amount of metal oxide,photocatalytic activity of the complex increased at first and then decreased.The CuO/ZnO/3A composite photocatalyst calcined at 400℃ for 5 h with 9.8% mass fraction of zinc and 28.6% of copper enabled 74.78% denitrification of the simulated oil system,after a reaction under visible light of 50 m L solution containing100 μg/g of pyridine for 150 min.
