Abstract

Dichlorodifluoromethane (CFC-12) is one of the typical compounds currently studied in the problem of Freon, which is responsible for the destruction of the ozone layer and abnormal climate change. Al2O3/ZrO2 solid catalyst was prepared, and the effects of the molar ratio of Al2O3 and ZrO2, calcination temperature, calcination time, and catalyst dosage of the catalyst on the decomposition rate of CFC-12 were studied. The results showed that the best conditions for the preparation of catalyst were as follows: molar ratio of Al2O3 to ZrO2 was 1, calcination temperature was 800 ℃, calcination time was 2 h, and the amount of catalyst was 1 g. The hydrolysis rate of CFC-12 composite material could reach 98.75%. The characteristics of the catalysts were characterized by XRD, XPS, SEM, EDS, BET, CO2-TPD and NH3-TPD.
