Highly Active and Stable Ni/La-Doped Ceria Material for Catalytic CO₂ Reduction by Reverse Water-Gas Shift Reaction.

ABSTRACT: The design of an active, effective, and economically viable catalyst for CO₂ conversion into value-added products is crucial in the fight against global warming and energy demand. We have developed very efficient catalysts for reverse water-gas shift (rWGS) reaction. Specific conditions of the synthesis by combustion allow the obtention of macroporous materials based on nanosized Ni particles supported on a mixed oxide of high purity and crystallinity. Here, we show that Ni/La-doped CeO₂ catalysts─with the "right" Ni and La proportions─have an unprecedented catalytic performance per unit mass of catalyst for the rWGS reaction as the first step toward CO₂ valorization. Correlations between physicochemical properties and catalytic activity, obtained using a c
