Recent advances in electrochemical reduction of CO2

The electrochemical CO2 reduction (ECR) into fuels and feedstocks enables the storage of intermittent renewable electricity and, ultimately, a net reduction of greenhouse gas emissions, which therefore have been paid much attention. In this article, the advances on ECR in the past 3 years are reviewed with focus on the developments of electrolytes, electrocatalysts, and new strategies for ECR.
