摘要

Recent years have witnessed increasing damage to water ecosystems, elevating the importance of environmental protection. The activation of persulfate using modified biochar materials has attracted widespread attention due to its efficient generation of highly oxidative reactive species, enhanced degradation of refractory pollutants, facile preparation, and environmental benignity. However, comprehensive analyses of research trends and advances in this field remain scarce. To address this gap, this study retrieved relevant publications from the Web of Science Core Collection database (2011—2024). After rigorous screening, 839 research articles were selected for bibliometric visualization analysis using CiteSpace, RStudio, and VOSviewer. Through temporal analysis of publication outputs, identification of top 10 highly cited papers, keyword co-occurrence clustering, and timezone mapping, this study systematically reveals the evolutionary patterns and research hotspots in this field. By examining cutting-edge research, analyzing current frontiers, and synthesizing development trends, this work provides valuable insights and guidance for future research directions.
