The embedding microbial fuel cell (MFC) into constructed wetlands (CW) to form CW-MFC bears the potential to obtain bioelectricity and a clean environment. In this study, a bibliometric analysis using VOSviewer based on Web of Science data was conducted to provide an overview by tracing the development footprint of this technology. The countries, institutions, authors, key terms, and keywords were tracked and corresponding mapping was generated. From 2012 to September 2020, 442 authors from 129 organizations in 26 countries published 135 publications in 42 journals with total citation of 3,139 times were found. The key terms analysis showed four clusters: bioelectricity generation performance, mechanism study, refractory pollutants removal, and enhanced conventional contaminants removal. Further research themes include exploring the biochemical properties of electrochemically active bacteria; emerging contaminants removal; effective bioelectricity harvest and the use; and biosensor development as well as scaling-up for real field application. The bibliometric results provide valuable references and information on potential research directions for future studies.

将微生物燃料电池（MFC）嵌入人工湿地（CW）中以形成CW-MFC具有获得生物电和清洁环境的潜力。在这项研究中，使用了基于Web of Science的VOSviewer的文献计量分析通过追踪该技术的发展足迹来进行数据收集以提供概述。跟踪国家，机构，作者，关键术语和关键字，并生成相应的映射。从2012年到2020年9月，来自26个国家/地区的129个组织的442位作者在42种期刊上发表了135种出版物，被总共引用3,139次。关键术语分析显示了四个集群：生物电发电性能，机理研究，难熔污染物的去除和常规污染物的增强去除。进一步的研究主题包括探索电化学活性细菌的生化特性；新出现的污染物去除；有效的生物电收获和利用；生物传感器开发以及扩大规模以用于实际应用。
