Selective and high-rate CO electroreduction by metal-doped covalent triazine frameworks: a computational and experimental hybrid approach.

The electrochemical CO reduction reaction (CORR) has attracted intensive attention as a technology to achieve a carbon-neutral society. The use of gas diffusion electrodes (GDEs) enables the realization of high-rate CORRs, which is one of the critical requirements for social implementation. Although both a high reaction rate and good selectivity are simultaneously required for electrocatalysts on GDEs, no systematic study of the relationship among active metal centers in electrocatalysts, reaction rate, and selectivity under high-rate CORR conditions has been reported.
