    Abstract: CoxZr1-xO2 catalyst was prepared by precipitation, hydrothermal, thermal decomposition and dipping methods. The effects of the preparation method on its structure and the oxidation per-formance of toluene were investigated. The physicochemical properties of the catalysts were characterized by TG, XRD, SEM, EDS and BET. The results showed that cobalt species and zirconium had good dispersion on the catalyst with uniform sphere. The specific surface area of the catalyst by hydrothermal was 82.3 m2·g-1 and the pore structure was developed. The good oxidized toluene performance of catalysts was related to species dispersion, specific surface area and pore structure. The complete oxidation of toluene conversion temperature was 260℃ under the conditions of the space velocity of 20000 mL·(g·h)-1 and the 0.1% concentration.
