Ni-MgO catalysts have been widely applied for carbon dioxide reforming (CDR) reaction due to their ability of anti-carbon formation. However, activation of Ni-MgO catalyst consumes considerable energy because of its very low reducibility. In this study, ZrO2, CeO2, and CeO2-ZrO2 promoted Ni-MgO catalysts were prepared via a facile coprecipitation method and applied to the CDR reaction. Among the prepared catalysts, the ZrO2-promoted Ni-MgO catalyst showed the highest methane conversion. The high catalytic performance of the ZrO2-promoted Ni-MgO catalyst is mainly due to easier reducibility, high Ni dispersion, and high specific surface area.
