Microbial electrosynthesis for clean utilization and high-value conversion of CO2: A bibliometric review

Harnessing microbial electrosynthesis (MES) to convert carbon dioxide into high-value products represents one of the most effective global strategies for green carbon emission reduction. This approach not only addresses greenhouse gas mitigation but also promotes resource utilization. To gain insight into the research landscape of MES in the high-value conversion of CO2, this review employs a bibliometric analysis of key literature and emerging research trends from 2010 to 2024 within the Web of Science Core Collection. Through network visualization, the study identifies the most influential countries, institutions, authors, and publications, as well as the co-occurrence patterns of highly cited papers and keywords in this field. Focusing on the main research hotspots, the review highlights the role of electroactive microorganisms, bioelectrodes, and MES reactors in MES applications. This bibliometric analysis provides a comprehensive overview of the progress and future directions in CO2 conversion via microbial electrosynthesis, offering valuable data-driven insights for researchers in this rapidly evolving field.
