Preparation and catalytic performance of layered Co-Al hydroxide monolithic catalyst
摘要
Abstract
The layered Co-Al hydroxide monolithic catalyst was prepared by hydrothermal method using CF(carbon felt)as carrier.The structure and morphology of catalyst were characterized by XRD(X-ray diffractometer),SEM(scanning electron microscope),XPS(X-ray photoelectron spectrometer)and BET(specific surface analyzer).The results show that the layered Co-Al hydroxide can be successfully prepared on the surface of CF at both 100℃and 120℃,and the morphology is flower-like.Compared with the catalyst obtained at 120℃,the catalyst obtained at 100℃has smaller grain size and higher specific surface area.The catalytic activity of the layered Co-Al hydroxide monolithic catalyst in activating PMS(potassium peroxymonosulfate)was evaluated by TCH(tetracycline hydrochloride)degradation experiment.The effect of different influencing factors on the degradation of TCH by PMS activated by layered Co-Al hydroxide monolithic catalyst was investigated.The results show that the degradation rate of TCH is 86％after 15 min reaction at catalyst dosage of 55 mg/L,PMS mass concentration of 100 mg/L,TCH initial mass concentration of 10 mg/L and pH of 7.The results of free radical trapping experiments show that the main active free radicals in the catalytic system are SO4-·and 1 O2.The cyclic experiment results show that the degradation rate of TCH by layered Co-Al hydroxide monolithic catalyst remains above 80％after ten cycles,indicating excellent cyclic stability.关键词
