【Abstract】 Biochar-loaded zero-valent iron composites are widely used in the environmental field as a new efficient remediation material with both adsorption and reduction effects. Based on the Web of Science core database, the research hotspots and trends of biochar-loaded zero-valent iron composites for environmental applications from 2013-2022 were analyzed by the bibliometric visualization application CiteSpace. The results showed that the researches of biochar-loaded zero-valent iron composites are at an emerging development stage, and the number of related articles is generally increasing by years. China had the highest total number of articles published and the largest international influence. The Chinese Academy of Sciences are the research institution with the highest number of publications and the highest degree of intermediary centrality. Researchers Mengfang Chen and Linbo Qian from the Chinese Academy of Sciences and Professor Bin Gao from the University of Florida were the most prolific team of scholars in terms of number of publications. After nearly a decade of development, researches had shown a tendency toward differentiation and the emergence of different emerging research frontiers. The focus of the researched were changed from the mechanismes of adsorption and removal of pollutants such as heavy metals and organic matter in polluted water by composite materials to the effects on environmental microorganisms and greenhouse effect. Developing new biochar-loaded zero-valent iron composite remediation materials; exploring the remediation and removal mechanisms of heavy metals, novel pollutants and composite pollution in polluted soil; investigating the degradation mechanisms of microbial communities and functional genes; and elucidating the regulatory mechanisms between microorganisms and greenhouse gas emissions may be the hot spot and trend for future research.更多还原
