Abstract

The first study of rational synthesis of triazine-based nanoporous frameworks as electrocatalysts for CO₂ reduction reaction (CO₂RR) was presented. The resulting optimized framework with rich pyridinic nitrogen-containing sites can selectively reduce CO₂ to CO in water with a high Faradic efficiency of ca. 82% under a moderate overpotential of 560 mV. The key of our success lies in the use of pyridine-based backbones as sacrificial groups inside the triazine framework for in situ generation of CO₂RR-active pyridinic N-doped sites during the high-temperature ZnCl₂-promoted polymerization process. We anticipate that this study may facilitate new possibilities for the development of porous organic polymers for electrochemical conversion of CO₂.
