摘要：水热碳化技术是解决环境污染和固体废物资源化利用的重要途径。为了明确水热炭处理环境中重金属的研究现状和发展趋势,基于Web of Science数据库,使用文献计量学软件VOSviewer和CiteSpace对该领域研究文献的年发文量、发文国家/地区、研究机构和作者进行计量学分析。结果表明:2011—2021年间,该领域研究的发文量显著增长,中国、美国和印度的发文量位居前三,其中中国的发文量占总发文量的57.17%,远超其他国家,主要的发文机构是中国科学院、中国科学院大学和中国科学技术大学;该领域的研究成果主要发表在Chemical Engineering Journal和Journal of Hazardous Materials等高影响因子期刊上。通过双图叠加分析,确定该领域的主要研究分布在环境、毒理、材料、物理等学科;此外,期刊共被引可视化及关键词聚类分析发现,当前水热炭处理重金属的研究主要集中在污水污泥的水热处理(重金属的去除和稳定)、去除重金属水热新型碳材料(石墨烯、纳米材料等)的研发和水热碳量子点对重金属的检测;关键词突现分析表明:近两年,“高效去除”“磁性生物炭”“低温”和“光催化降解”等关键词爆发,成为水热炭处理重金属领域的研究热点。本文对水热炭处理重金属领域的发展现状进行梳理,并对该领域未来的发展趋势进行预测,可为了解水热炭处理重金属领域的发展态势提供参考。
Hydrothermal carbonization technology is an important way to solve environmental pollution and resource utilization of solid waste.To clarify the research status and development trend of hydrochar treatment of heavy metals in the environment,econometric analysis of number of articles issued per year,country of publication,research institution and author are analyzed by using bibliometric software VOSviewer and CiteSpace based on Web of Science database.The results shows that the overall trend of the number of publications on heavy metals removal studies by hydrochar is increasing from 2011 to 2021.China,the United States and India are the top three.The number of papers published in China account for 57.17%of the total number of papers published in the world,far exceeding other countries.The major issuing institutions are Chinese Academy of Sciences,University of Chinese Academy of Sciences and University of Science and Technology of China.This field is mainly published in high?impact journals such as Chemical&Engineering Journal and Journal of Hazardous Materials.Through the double graph overlay analysis,it is suggested that the main research disciplines in this field are environment,toxicology,materials,physics,etc.Additionally,the journal co?citation visualization and keyword clustering analysis find that the current research on hydrochar treatment of heavy metals mainly focuses on the hydrothermal treatment of sewage sludge(removal and stabilization of heavy metals),and the exploration of new hydrochar materials(graphene,nanomaterials,etc.)to remove heavy metals and detection of heavy metals by hydrochar dots.Keyword emergent analysis shows that the keywords including‘efficient removal’‘magnetic biochar’‘low temperature’and‘photocatalytic degradation’have exploded in the past two years and will become a research hotspot in the field of hydrochar affecting heavy metals.This study sorts out the development status of the field of hydrothermal carbon treatment of heavy metals,and predicts the future development trend of this field,which can provide a reference for understanding the development trend of the field of hydrothermal carbon treatment of heavy metals.
