Upgrading CO2 to sustainable aromatics via perovskite-mediated tandem catalysis

Abstract The directional transformation of carbon dioxide (CO 2 ) with renewable hydrogen into specific carbon-heavy products (C 6+ ) of high value presents a sustainable route for net-zero chemical manufacture. However, it is still challenging to simultaneously achieve high activity and selectivity due to the unbalanced CO 2 hydrogenation and C–C coupling rates on complementary active sites in a bifunctional catalyst, thus causing unexpected secondary reaction. Here we report LaFeO 3 perovskite-mediated directional tandem conversion of CO 2 towards heavy aromatics with high CO 2 conversion (> 60%), exceptional aromatics selectivity among hydrocarbons (> 85%), and no obvious deactivation for 1000 hours.…
