英文摘要	Ordered mesoporous TiO2–ZrO2 materials were prepared by evaporation-induced self-assembly (EISA). The CeSn/TizZr10-zOx catalysts were prepared by impregnation method, and its catalytic performance was evaluated for the removal of 1,2-dichlorobenzene (o-DCB). The structure and properties of CeSn/TizZr10-zOx were characterized by N2 adsorption-desorption, XRD, Raman, SEM, TEM, XPS and temperature programmed techniques. The results showed that Ce and Sn oxides were highly dispersed on TiO2–ZrO2 surface. Ti–Zr mixed oxides not only contributed to the formation of ordered mesopores, but also to the formation of strong acid sites. When the molar ratio of Ti/Zr was 6:4, the catalyst exhibited the excellent catalytic activity and outstanding stability and repeatability for the o-DCB elimination reaction because of its superior chlorine resistance. Furthermore, the reaction mechanism of o-DCB catalytic oxidation reduction was proposed based on surface lattice oxygen. © 2020 Elsevier Inc.
