Abstract
In this study, CeO2/ZrO2-TiO2-x%Mg (CTZ-x%Mg) composite oxide was prepared by hydrothermal synthesis and impregnation. The performance of the catalyst for the combustion reaction of methylene chloride (DCM) was evaluated. CeO2/ZrO2-TiO2-4%Mg (CTZ-4%Mg) showed good catalytic activity, anti-chlorine toxicity and CO2 and HCl selectivity. The prepared catalyst was characterized and analyzed by XRD, BET, XPS, H2-TPR and NH3-TPD. The results showed that doping with the alkaline earth metal Mg enhanced the surface adsorption oxygen content and the lattice oxygen mobility of the catalyst carrier and promoted the auxiliary catalytic activity of ZrO2-TiO2. At the same time, the strong interaction between Mg-Ce-O induced the conversion of Ce3+ to Ce4+ on the catalyst surface while inhibiting the growth of CeO2 crystals and improving redox performance.
