Microalgae CO sequestration has gained considerable attention in the last three decades as a promising technology to slow global warming caused by CO emissions. To provide a comprehensive and objective analysis of the research status, hot spots, and frontiers of CO fixation by microalgae, a bibliometric approach was recently chosen for review. In this study, 1561 articles (1991-2022) from the Web of Science (WOS) on microalgae CO sequestration were screened. A knowledge map of the domain was presented using VOSviewer and CiteSpace. It visually demonstrates the most productive journals (Bioresource Technology), countries (China and USA), funding sources, and top contributors (Cheng J, Chang JS, and their team) in the field of CO sequestration by microalgae. The analysis also revealed that research hotspots changed over time and that recent research has focused heavily on improving carbon sequestration efficiency. Finally, commercialization of carbon fixation by microalgae is a key hurdle, and supports from other disciplines could improve carbon sequestration efficiency.
微藻 CO2 固碳在过去三十年中受到了相当大的关注，因为它是一种有前途的技术，可以减缓由 CO2 排放引起的全球变暖。为了对微藻 CO2 固定的研究现状、热点和前沿进行全面和客观的分析，最近选择了一种文献计量学方法进行综述。在这项研究中，从 Web of Science (WOS) 筛选了 1561 篇关于微藻 CO2 固碳的文章（1991-2022 年）。使用 VOSviewer 和 CiteSpace 呈现了该领域的知识图谱。它直观地展示了该领域最具生产力的期刊（《生物资源技术》）、国家（中国和美国）、资金来源和主要贡献者（Cheng J、Chang JS 及其团队）。分析还表明，研究热点随时间而变化，最近的研究重点是提高碳固存效率。最后，微藻固碳的商业化是一个关键障碍，其他学科的支持可以提高碳固存效率。
