The field of electrochemical carbon dioxide reduction has developed rapidly during recent years. At the same time, role anodic half-reaction received considerably less attention. In this Perspective, we scrutinize reports on best-performing CO2 electrolyzer cells from past 5 years, to shed light oxygen evolution catalyst. We analyze how different cell architectures provide local chemical environments at anode surface, which in turn determines pool applicable catalysts. uncover factors that led either a strikingly high current density operation or an exceptionally long lifetime. On basis our analysis, set criteria have be fulfilled by catalyst achieve performance. Finally, outlook using alternative reactions (alcohol oxidation is discussed as example), resulting high-value products and higher energy efficiency for overall process.

Abstract Electroreduction of carbon dioxide (CO 2 ) into high‐value and readily collectable liquid products is vital but remains a substantial challenge due to the lack highly efficient robust electrocatalysts. Herein, Bi‐based metal‐organic framework (CAU‐17) derived leafy bismuth nanosheets with hybrid Bi/BiO interface (Bi NSs) developed, which enables CO reduction formic acid (HCOOH) high activity, selectivity, stability. Specially, flow cell configuration employed eliminate diffusion effect molecules simultaneously achieve considerable current density (200 mA cm −2 for industrial application. The faradaic efficiency transforming HCOOH can over 85 or 90% in 1 m KHCO 3 KOH at least 10 h despite that exceeds 200 , outperforming most reported electroreduction catalysts. surface boosts adsorption protects structure as‐prepared nanosheets, benefits its activity stability electroreduction. This work shows modifying electrocatalysts by oxygen groups promising pathway regulate selective HCOOH.

Abstract The electroreduction of CO 2 to value‐added chemicals such as is a promising approach realize carbon‐neutral energy cycle, but still remains big challenge including low current density. Covalent organic frameworks (COFs) with abundant accessible active single‐sites can offer bridge between homogeneous and heterogeneous electrocatalysis, the electrical conductivity limits their application for reaction (CO RR).
