The physicochemical properties of the prepared catalysts were studied by using the XRD, BET, H<jats:sub>2<\/jats:sub>\u2010TPR, and H<jats:sub>2<\/jats:sub>\u2010TPD. The effects of the catalyst structure and Zr dosage on CO<jats:sub>2<\/jats:sub>\u00a0hydrogenation performances were also investigated. The porous Ce<jats:sub>x<\/jats:sub>Zr<jats:sub>1\u2010x<\/jats:sub>O<jats:sub>2<\/jats:sub>\u00a0support prepared by the hard\u2010template method has a large specific surface area and developed pore structure. With the increment of Zr dosage, the crystal phase structure of the prepared porous Ce<jats:sub>x<\/jats:sub>Zr<jats:sub>1\u2010x<\/jats:sub>O<jats:sub>2<\/jats:sub>\u00a0support transforms from cubic phase to tetragonal phase. The Co\u2013Ce\u2013O\u2013Zr solid solution was formed in the corresponding catalyst by introducing an appropriate amount of Zr and significantly improved the reducibility of the Co<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>\/Ce<jats:sub>x<\/jats:sub>Zr<jats:sub>1\u2010x<\/jats:sub>O<jats:sub>2<\/jats:sub>\u00a0precursors, by which the interaction between the active Co<jats:sup>0<\/jats:sup> and support was enhanced. At the same time, it is conducive to the formation of oxygen vacancies and highly dispersed Co<jats:sup>0<\/jats:sup>\u00a0to promote the hydrogenation active sites to be formed in the corresponding catalyst, and thus promoting the CO<jats:sub>2<\/jats:sub>\u00a0hydrogenation. The porous CoCe<jats:sub>0.99<\/jats:sub>Zr<jats:sub>0.01<\/jats:sub>\u00a0catalyst with the Zr content of 1.0 mol% has the best catalytic performances. At 400 \u00b0C and atmospheric pressure, the CO<jats:sub>2<\/jats:sub>\u00a0hydrogenation conversion and CH<jats:sub>4<\/jats:sub>\u00a0selectivity on the CoCe<jats:sub>0.99<\/jats:sub>Zr<jats:sub>0.01<\/jats:sub>\u00a0catalyst reached 59.8% and 94.7%,
