摘要
单原子催化剂具有催化活性高、选择性强等优点,在非均相催化领域显示出独特的优势.碳基材料作为单原子催化剂的常用载体,具有比表面积大、价格低廉、易于获取等特点,近年来受到广泛关注.随着碳基单原子催化研究的不断深入,相关论文的发表量增长迅速,传统的文献分析方法存在可视化程度低、时间跨度短、覆盖范围小等问题.本文利用CiteSpace文献计量软件对Web of Science核心数据库中 2015 年 1 月—2023 年 3 月收录的378 篇相关文献进行了可视化分析,讨论了该领域的研究进展及研究热点.结果表明:碳基单原子催化的研究热点主要集中在电催化领域,应用最广泛的载体是氮掺杂碳材料;存在的主要问题有难以催化复杂反应、反应机理不够清晰、配位环境难以精准调控等.本文结果可为碳基单原子催化的研究提供参考.
Abstract
Single-atom catalysts have shown many advantages in the field of heterogeneous catalysis,including high catalytic activity and selectivity.As a common carrier of single-atom catalysts,carbon-based materials have attrac-ted extensive attention in recent years due to their large specific surface area,low price and easy access.With the deepening of carbon-based single-atom catalysis research,the number of related papers published has increased rapidly.Traditional literature analysis methods suffer from problems such as low visualization,short time span,and small coverage.This paper uses CiteSpace bibliometric software to visually analyze 378 papers included in the Web of Science core database from January 2015 to March 2023,and discusses the research progress and hotspots in this field.The results show that the research hotspots for carbon-based single-atom catalysis are mainly concentrated in the field of electrocatalysis,and the most widely used carrier is nitrogen-doped carbon material.The main problems are that it is difficult to catalyze complex reactions,the reaction mechanism is not sufficiently clear,and the coordi-nation environment is difficult to accurately control.The results of this paper can provide a reference for the future study of carbon-based single-atom catalysis.
