摘要
与普通硅酸盐水泥相比,粉煤灰基地质聚合物可大幅减少生产过程中的碳排放,提供了开发新型绿色高附加值产品的新途径。近10年来,粉煤灰基地质聚合物领域发文近6000篇,有必要进行基于科学计量学方法的定量分析,为粉煤灰基地质聚合物研究及粉煤灰的绿色综合利用提供参考。本文检索Web of Science核心合集及中国知网学术文献总库中文献,基于CiteSpace分析发文群体和关键词,构建共现网络,分析研究趋势和热点。结果表明:2013-2023年粉煤灰基地质聚合物的研究热度持续保持;中、英文文献核心作者发文频次占比均超过5%,英文文献发文机构间合作更紧密;关键词共现图谱以及聚类和突现分析结果说明相关研究集中于力学性能和吸附性能,且后者逐渐成为近年的研究热点;粉煤灰基地质聚合物及其复合材料捕集CO_(2)气体和去除水体污染物的性能和机制仍为应用的热点课题之一。反应体系的化学组成是粉煤灰基地质聚合物力学性能和吸附性能区别于其他地质聚合物的主要因素,利用化学组成协同调控力学性能与吸附性能的研究是今后的一个主要发展趋势。
Geopolymers made from fly ash provide a promising alternative to ordinary Portland cement,with significant reductions in associated carbon emissions and the potential for developing high-value-added and green products from fly ash.In the past 10 years,nearly 6000 articles have been published in the field of fly ash-based geopolymers,and it is necessary to conduct a quantitative analysis by scientometric methods to provide a reference for the research of fly ash-based geopolymers and the green integrated utilization of fly ash.This review used scientometric methods to analyze literatures from the Web of Science Core Collection and the China National Knowledge Infrastructure repository to gain insights into the research trends and hotspots of fly ash-based geopolymers.We conducted CiteSpace-based author and institution analyses and constructed a co-occurrence network to examine"fly ash"and"geopolymer"research.Our findings indicated that the number of publications on fly ash-based geopolymers increased yearly from 2013 to 2023,with sustained research interest.The core authors in Chinese and English literature publications accounted for more than 5%of respective publication frequencies.Institutions collaborated more closely in English literature than in Chinese literature.Keywords co-occurrence mapping,clustering,and emergence analyses suggested that recent research on fly ash-based geopolymers had focused on mechanical and adsorption properties,including the trapping of CO_(2) and the removal of nutrients,heavy metals,and organic matter from water bodies.The chemical composition of the reaction system is the main factor that distinguishes the mechanical and adsorption properties of fly ash-based geopolymers from other geopolymers.Using chemical composition to regulate the mechanical and adsorption properties synergistically is a major trend for future research.
