To better grasp developments and trends in research on green energy and environmental technologies, the published literatures in the Web of Science Core Collection database from 1998 to 2020 were utilized to reveal critical information and guidance on what has been investigated, and what are the changes in research interests using a bibliometric method. Herein, yearly quantitative distribution of literatures, author contribution and collaboration, productive and influential institutions and countries/territories, co-citation analysis, keywords co-occurrence analysis, and research frontier identification are analyzed via information visualization technology. The results show that the publications on green energy and environmental technologies have grown exponentially, that China, the USA, and Italy are the most active countries, but the global cooperation is not close at present. The research frontier identification results reveal that the categories of energy, wastewater, and performance remain stable, while the trending up and emerging categories of catalyst and CO emission show clear shift over the last decade, indicating that catalytic production of clean energy and value-added chemicals, strategies to reduce greenhouse gas emissions, and other related studies to solve the global energy crisis and environmental problems are the research frontiers. This bibliometric study provides unique insights and offers research guidance on green energy and environmental technologies.
为了更好地掌握绿色能源与环境技术的研究进展和趋势，利用科学网核心合集数据库中1998年至2020年发表的文献，采用文献计量学方法揭示已开展研究的关键信息及指导意见，以及研究兴趣的变化情况。在此，通过信息可视化技术分析文献的年度定量分布、作者贡献与合作、高产和有影响力的机构及国家/地区、共被引分析、关键词共现分析以及研究前沿识别。结果表明，绿色能源与环境技术方面的出版物呈指数级增长，中国、美国和意大利是最活跃的国家，但目前全球合作并不紧密。研究前沿识别结果显示，能源、废水和性能类别保持稳定，而催化剂和CO排放类别在过去十年中呈上升趋势且属于新兴类别，表明清洁能源和增值化学品的催化生产、减少温室气体排放的策略以及其他解决全球能源危机和环境问题的相关研究是研究前沿。这项文献计量学研究为绿色能源与环境技术提供了独特见解并给出了研究指导。
