摘　　要：采用浸渍法制备了以HZSM-5为载体的CoFe2O4光催化剂,利用X射线衍射仪、UV-Vis漫反射光谱仪、氮吸附比表面仪对样品进行了表征,发现HZSM-5表面负载有CoFe2O4复合氧化物,且负载后的比表面积明显增大。通过对HZSM-5负载CoFe2O4光催化剂的光催化性能研究得到12%CoFe2O4/HZSM-5在6 h后还原CO2得到甲酸的产量为6896.98μmol/g-cat。CoFe2O4 photocatalyst was prepared with HZSM-5 as carrier,and using X-ray diffraction,UV-Vis diffuse reflectance spectroscopy,the samples were characterized and found that the surface of HZSM-5 loaded with CoFe2O4 composite oxide.Through the study of photocatalytic performance of the HZSM-5 load CoFe2O4 photocatalyst,12% CoFe2O4/HZSM-5 methanoic acid was got and the yield may achieve 6896.98 μmol/g-Cat when irradiation time was 6 h.
