| Abstract: | CuO/CoFe2O4 particles were prepared by sol gel method and CuO/CoFe2O4 TiO2 composite catalysts were synthesized by CuO/CoFe2O4 and Degussa P25.Photocatalytic activity of as prepared nanocomposites was investigated using the degradation of methylene blue aqueous solution under visible light irradiation as the probe reaction.The catalysts were characterized by XRD,SEM,TEM and UV-Vis DRS.The results showed that CuO/CoFe2O4 nanoparticles deposited on the surface of Degussa P25 nanopariticles were dispersed well and the average size was about 60 nm.The influence of catalyst types,P25 contents in CCFP（CuO/CoFe2O4 doped with P25）,light intensity,calcination temperature and methylene blue adsorption rate was studied.The results indicated that the catalyst CCFP-70 doped with 70wt% P25 for degradation of methylene blue exhibited better activity than that of pure TiO2 and P25.The degradation rate of methylene blue reached 99% under 250 W xenon lamp for 60 minutes. |
