| Abstract: | The catalytic oxidative degradation of 2,4-dichlorophenol(2,4-DCP)was studied.The results indicated that CuO/γ-Al2O3 exhib-ited high activity for the reaction.Adding alkaline-earth metal oxides into CuO/γ-Al2O3 improved the liberation rate of chloride ion from 2,4-DCP remarkably and SrO was the most efficient.The 2,4-DCP conversion and the liberation rate of chloride ion reached 100% when the CuO/γ-Al2O3-SrO catalyst was used 3 times.The results of X-ray diffraction and the temperature-programmed-desorption of ammonia indi-cated that the catalyst with good dispersion of CuO particles and a less amount of acid sites was favorable for the efficient oxidative degrada-tion of 2,4-DCP.A probable pathway of the oxidative degradation for 2,4-DCP over the copper-based catalyst was suggested. |
