Upgrading CO₂ to sustainable aromatics via perovskite-mediated tandem catalysis.

ABSTRACT: The directional transformation of carbon dioxide (CO₂) with renewable hydrogen into specific carbon-heavy products (C₆₊) 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 CO₂ hydrogenation and C-C coupling rates on complementary active sites in a bifunctional catalyst, thus causing unexpected secondary reaction. Here we report LaFeO₃ perovskite-mediated directional tandem conversion of CO₂ towards heavy aromatics with high CO₂ conversion (> 60%), exceptional aromatics selectivity among hydrocarbons (> 85%), and no obvious deactivation for 1000 hours. This is enabled by disentangling the C
