Ethanol synthesis via catalytic CO2 hydrogenation over multi-elemental KFeCuZn/ZrO2 catalyst

The prepared KFeCuZn/ZrO 2 catalyst displayed a higher efficiency in CO 2 hydrogenation to ethanol (STY EtOH ∼ 5.4 mmol g cat −1 h −1 ). The mechanistic studies emphasized the importance of all components for ethanol synthesis.
