Remarkable Carbon Dioxide Hydrogenation to Ethanol on a Palladium/Iron Oxide Single-Atom Catalyst
Résumé
CO2 hydrogenation into value-added chemicals is one of the most investigated methods to reduce CO 2 emissions into the atmosphere and thereby contribute to a sustainable chemical industry. While the catalytic hydrogenation of CO 2 into methanol and synthetic hydrocarbons is well established, the effective and selective transformation of CO2 into higher alcohols is still challenging. Here we show that Pd single atoms anchored on the surface of Fe3O4 are very active for the hydrogenation of CO 2 into ethanol at 300 °C, even at atmospheric pressure. By comparing various Pd/MOx catalysts we conclude that the metal/oxide interface has a strong influence on the catalytic behavior.
