The influence of exogenous amines on the electrochemical CO2 reduction activity of a cobalt–pyridyldiimine catalyst

Abstract

Studying the interactions between CO₂ sorbents and electrocatalysts for the electrochemical CO₂ reduction reaction (e-CO₂RR) can offer viable strategies to advance the development of the Reactive Capture of CO₂ (RCC). In this report we studied the effect of amines on the performance of the [Co(PDI-Py)] catalyst for the e-CO₂RR. The presence of amines shifts the onset potential for the e-CO₂RR more positive and increases the catalytic activity while maintaining the high Faradaic efficiency (≥90%) for CO production.
