Hydrogenation of CO2 to aromatics with selectivity of 73% among hydrocarbons at a single-pass conversion of 14% is achieved over a tandem catalyst. A thermodynamic coupling between CO2 hydrogenation and aromatics formation was effectively conducted through the intermediate CHxO species. It was found that the presence of H2O and CO2 not only facilitates aromatics production but also suppresses the formation of polycyclic aromatics, resulting in highly stable catalytic performance.
