Abstract A series of the Co/Ce x Zr 1‐x O 2‐δ catalysts were prepared by precipitation‐impregnation method using Ce‐O‐Zr solid solutions with different Ce/Zr mole ratios as support and used for CH 4 /CO 2 reforming to produce hydrogen. The physicochemical properties precursors studied H ‐TPR, XRD, CO ‐TPD, relationship between performances was established. CeO ZrO can dissolve in each other form corresponding solutions, which promote migration atoms lattice facilitate oxygen vacancies be formed. formed solution improve metal Co anchored on surface active centers high dispersion. An appropriate ratio reduction catalyst precursors, Co0 species, vacancies, basic surface, thereby enhancing adsorption activation abilities reactants molecules. 0.15 0.85 a 0.18 achieved conversions 67.3% 42.7% at atmospheric pressure 700 °C, respectively.
