State-of-the-art thermocatalytic systems for CH4 and CO production via CO2 hydrogenation: critical comparison, mechanistic considerations and structure-performance insights

Abstract The unprecedented increase of atmospheric CO2 concentration and the associated climate change calls for the urgent implementation of CO2 mitigation approaches. Among the various proposed measures, CO2 capture from several industrial point sources or directly from air and its subsequent hydrogenation via renewable H2 towards value-added products formation has gained particular attention. Specifically, the production of CO or CH4 is of great importance for the eventual generation of liquid fuels or synthetic natural gas, respectively. Herein, an overview of the state-of-the-art noble an... Mehr ...
