Advances in surface modification of cathode materials in microbial electrosynthesis systems for enhanced carbon sequestration and utilization
The increasingly severe impact of the greenhouse effect on human society has intensified the research and development of carbon capture and utilization(CCU)technologies.Microbial electrosynthesis system(MES),as a novel biotechnology for CCU,have emerged as a promissing approach for CO2 fixation and the production of high-value chemicals,thus gain increasingly significant attention from various researchers.This review beigins with an overview of the mechanisms of carbon fixation and acetate production in MES.It then summarizes the latest research progress on commonly used MES cathode materials and their surface modification methods to optimize their performance.Finally,enhancement measures and future perspectives for improving the effiiency and productivity of carbon fixation and acetate production in MES,which may provide technical support for broader application of MES in carbon fixation and acetate production.
