Comparison of the Promoted CuZnM x O y (M: Ga, Fe) Catalysts for CO 2 Hydrogenation to Methanol

Up to date, selective hydrogenation of undesirable CO 2 to value-added chemicals is of great interest. To address this issue, the doped CuZnM (M: Ga, Fe) catalysts were synthesized by a facile microwave-assisted technique and its activity towards to CO 2 hydrogenation were evaluated. Indeed, the characterization results revealed the positive impact of the promoters on Cu dispersion and the total basicity etc., which were critical for CO 2 adsorption/conversion. Interestingly, the Fe dopants accelerated the formation of desirable C 2 + oxygenates (ethanol and n-propanol). Graphical Abstract
