Cover Picture: A Stable and Conductive Covalent Organic Framework with Isolated Active Sites for Highly Selective Electroreduction of Carbon Dioxide to Acetate (Angew. Chem. Int. Ed. 36/2022)

Abstract

Electroreduction of CO2 to acetate provides a promising strategy to reduce CO2 emissions and store renewable energy, but acetate is usually a by-product. A covalent organic framework with isolated active sites for highly selective electroreduction of CO2 to acetate was revealed by Pei-Qin Liao and co-wokers in their Communication (DOI: 10.1002/anie.202206470). The copper-phthalocyanine active site with high electron density is conducive to the key step of C−C coupling of *CH3 with CO2 to produce acetate, and can avoid the coupling of *CO with *CO or *CHO to produce ethylene and ethanol.
