Effect of Calcination Temperature on the Synthesis of Ni-based Cerium Zirconate for Dry Reforming of Methane

Dry reforming of methane (DRM) represents an alluring approach to the direct conversion of CO2 and CH4, gases with the highest global warming potential, into syngas, a value-added intermediate used in chemical industry. In this study, mixed oxide structures of cerium and zirconium doped with 10 wt%...
