Up to date, selective hydrogenation of undesirable CO2 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 CO2 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 CO2 adsorption/conversion. Interestingly, the Fe dopants accelerated the formation of desirable C-2(+) oxygenates (ethanol and n-propanol). [GRAPHICS] .
