基于文献计量分析的多孔碳吸附研究进展

为深入了解多孔碳在吸附领域研究的现状和前沿动态，以Web of Science （WoS）中Science Citation Index Expanded （SCI-E）引文数据库和CNKI数据库为数据源，使用Bibliometrix、Bibliometric平台和VOSviewer软件等对相关文献进行定量分析.结果表明，1997~2021年共发表SCI文献3566篇，文章数量总体呈逐年递增的趋势，近5a发文量上升速度较快，中国学术期刊共发表183篇文献；中国的发文总量及独立发文量均位居榜首，总量达1653篇，但平均被引频次相对较低；领域内主要研究力量分布在中国、美国、印度等地，且具有较大学术影响力的各作者间合作频繁.2010年至今温室气体中CO₂排放与多孔碳吸附议题之间有着十分紧密的学术联系，CO₂捕集将是碳中和课题下的一个持续研究热点.此外，开发和应用廉价、绿色、可持续的生物质资源制备性能优异的多孔碳材料是未来碳材料领域的持续目标之一，对于吸附机理的深入研究也将成为未来发展的方向之一.

Recent advances in porous carbon adsorption based on bibliometric analysis

To review the states and frontier of the art of porous carbon adsorption, Science Citation Index Expanded (SCI-E) citation database in Web of Science (WoS) and CNKI database were applied as the main data resources. The detailed literature analysis was conducted by Bibliometrix, Bibliometric platform and VOSviewer software. 3566SCI articles were published since 1997 to 2021, the overall trend of the number of articles was increasing. The number of publications increased rapidly in the past 5 years. 183 articles were published in Chinese academic journals. China ranking in the first place in terms of the total number of publications (1653articles) and independent publications, however, the average citation frequency was relatively lower than others. The main research forces were located in China, the United States and India, and there were frequent collaborations among authors with great academic influence. There was a strong academic link between CO₂ emissions and porous carbon adsorption in greenhouse gases since 2010, and CO₂ capture will be an ongoing research hotspot under the worldwide topic of carbon neutrality. The development and engineering application of low-cost, green and sustainable biomass resources to produce porous carbon materials will be drawn increasing attention in the future. In-depth understand of the adsorption mechanism will also be one of the future research directions.
