Construction of efficient and stable low-temperature reverse-bias bipolar membrane electrolyser for CO2 reduction
Electrochemical conversion of CO2 and H2O to value-added products is an attractive approach for sustainable chemical production.Significant progress has been made in the past few decades in improving activity and selectivity,advancing this technology to practical application.Considering the next step for the electrochemical CO2 reduction reaction,improving carbon utilisation efficiency,stability,and energy efficiency are essential.Bipolar membrane(BPM)-based electrolysers,which allow electrodes to be operated under different pH,are advantageous to tackle the challenge men-tioned above.Herein,we introduced the current status of CO2 electrolysers,followed by configura-tion,challenges,progress and outlook for combining reverse-bias BPM with different types of elec-trolysers.Our aim is to provide insight into developing carbon-efficient and energy-efficient CO2RR systems towards practical application.
