Reducible oxide (CeO2, ZrO2, and CeO2-ZrO2) promoted Ni-MgO catalysts for carbon dioxide reforming of methane reaction

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, ZrO 2 , CeO 2 , and CeO 2 -ZrO 2 promoted Ni-M...

Summary: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, ZrO 2 , CeO 2 , and CeO 2 -ZrO 2 promoted Ni-MgO catalysts were prepared via a facile coprecipitation method and applied to the CDR reaction. Among the prepared catalysts, the ZrO 2 -promoted Ni-MgO catalyst showed the highest methane conversion. The high catalytic performance of the ZrO 2 -promoted Ni-MgO catalyst is mainly due to easier reducibility, high Ni dispersion, and high specific surface area.
