Abstract: Ni/ZrO2 catalysts with different phase compositions and crystal sizes of ZrO2 nanoparticles were prepared and used to catalyze the methane reforming reaction with CO2. Catalyst characterizations with XRF, XRD, TEM, TPR and H2-TPD show that highly active and stable Ni/ZrO2 catalysts are nanocomposites of comparably sized metallic Ni and ZrO2 nanoparticles. The phase composition of ZrO2 in the catalysts has little effect on the catalytic stability.

Key words: Nickel catalyst, Zirconia, Crystal phase composition, Nanocomposite catalyst, CO2 reforming of CH4
