Boosting the methanol selectivity in CO2 hydrogenation over a MOF-derived CuZn@CN catalyst via Rb incorporation

Abstract

The highly selective hydrogenation of CO₂ to methanol has been achieved through the simultaneous utilization of alkali metals and Co as promoters over Cu–Zn@CN catalysts derived from MOF. Rb facilitates the dissociation of CO₂ in the aqueous phase at relatively mild conditions to yield methanol with a selectivity of 89%.
