Abstract: Dry reforming of methane or ethanol is a perspective way to transform two greenhouse gases as well as a model reactions for biofuels transformations. Ni-containing catalysts are attractive in these reactions due to their high activity and low price. Mixed Ce1−xZrxO2−δ oxides are promising catalysts supports due to their high oxygen mobility and reactivity. In our work Ce1−xZrxO2−δ doped with Nb, Ti were synthesized using supercritical fluid technology. The influence of the contact time, the type of supercritical fluid, the temperature and pressure on the degree of crystallization, the size of the crystallites, the specific surface and the morphology of the particles were investigated. The supporting of the active metal - nickel (2 to 10 wt.%) onto the oxides was done in two ways: the deposition of nickel in a onepot supercritical synthesis in parallel with the synthesis of a mixed oxide and insipient wetness impregnation of oxide support with nickel nitrate solution. The obtained catalysts were characterized by physical-chemical methods and tested in dry reforming of methane and ethanol reactions. The work was supported by the Russian Science Foundation, Project 18-73-10167.
