Bifunctional catalysis coupling CO2 to methanol and methanol to hydrocarbons is a promising strategy for the direct hydrogenation of CO2 into aromatics. However, selective conversion of CO2 and H2 into aromatics is still challenging due to the high unsaturation degree and complex structures of aromatics. Though, there is still lack of efficient catalysts to convert CO2 to methanol with high activity and high methanol selectivity at high temperature above 300°C. The synergistic interaction between two components in bimetal catalysts is one of the crucial factor in determining catalytic performance. Herein, we report the ZnO-ZrO2 bimetal catalysts synthesized with different methods to highlight the interactions between the two components in controlling the catalytic performance of catalysts. Furthermore, a tandem catalyst comprising of ZnO-ZrO2 and HZSM-5 used for one-pass conversion of CO2 to aromatics. |
