The anthropogenic emission of carbon dioxide (CO) into the atmosphere is recognized as the main contributor to global climate change. To date, scientists have developed various strategies, including CO utilization technologies, to reduce global carbon emissions. This paper presents the global scientific landscape of the CO utilization research from 1995 to 2019 based on a bibliometric analysis of 1875 publications extracted from Web of Science. The findings indicate a major increase in the number of publications and citations received from 2015 to 2019, denoting a fast-emerging research trend. The dynamics of global CO utilization research is partly driven by China's policies and research funding to promote low-carbon economic development. Applied Energy is recognized as a core journal in this research topic. The utilization of CO is a multidisciplinary topic that has progressed by multidimensional collaborations at the country and organizations levels, while the formation of co-authorship networks at the individual level is mostly influenced by the authors' affiliations. Keyword co-occurrence analysis reveals a rapid evolution in the CO utilization strategies from chemical fixation in carbonates and epoxides to pilot-scale testing of power-to-gas technologies in Europe and the USA. The development of efficient power-to-fuel technologies and biological utilization routes (using microalgae and bacteria) will probably be the next research priorities in CO utilization research.
人为向大气排放二氧化碳（CO）被认为是导致全球气候变化的主要因素。迄今为止，科学家们已经开发出各种策略，包括 CO 利用技术，以减少全球碳排放。本文基于从 Web of Science 中提取的 1875 篇出版物的文献计量分析，展示了 1995 年至 2019 年 CO 利用研究的全球科学格局。研究结果表明，2015 年至 2019 年，出版物数量和引文数量大幅增加，表明这是一个快速发展的研究趋势。全球 CO 利用研究的动态部分是由中国的政策和研究资金推动低碳经济发展所驱动的。《应用能源》被认为是这一研究主题的核心期刊。CO 的利用是一个多学科的课题，通过国家和组织层面的多维合作取得了进展，而个人层面的合著网络的形成主要受作者所属机构的影响。关键词共现分析揭示了 CO 利用策略从碳酸盐和环氧化物中的化学固定到欧洲和美国的电力到天然气技术的试点规模测试的快速演变。高效的电力到燃料技术和生物利用途径（使用微藻和细菌）的发展可能将成为 CO 利用研究的下一个研究重点。
