The alarming levels of carbon dioxide (CO) are an environmental problem that affects the economic growth of the world. CO emissions represent penalties and restrictions due to the high carbon footprint. Therefore, sustainable strategies are required to reduce the negative impact that occurs. Among the potential systems for CO capture are microalgae. These are defined as photosynthetic microorganisms that use CO and sunlight to obtain oxygen (O) and generate value-added products such as biofuels, among others. Despite the advantages that microalgae may present, there are still technical-economic challenges that limit industrial-scale commercialization and the use of biomass in the production of added-value compounds. Therefore, this study reviews the current state of research on CO capture with microalgae, for which bibliometric analysis was used to establish the trends of the subject in terms of scientometric parameters. Technological advances in the use of microalgal biomass were also identified. Additionally, it was possible to establish the different cooperation networks between countries, which showed interactions in the search to reduce CO concentrations through microalgae.
二氧化碳（CO）含量水平过高令人担忧，这是一个影响世界经济增长的环境问题。CO 排放代表着高额碳足迹带来的罚款和限制。因此，需要采取可持续的策略来减少由此产生的负面影响。在 CO 捕获的潜在系统中，微藻是一种。微藻被定义为利用 CO 和阳光获取氧气（O）并生成附加值产品（如生物燃料等）的光合微生物。尽管微藻可能具有优势，但仍存在技术经济方面的挑战，限制了其在工业规模商业化和利用生物质生产附加值化合物方面的应用。因此，本研究对利用微藻进行 CO 捕获的研究现状进行了综述，为此采用了文献计量分析来根据科学计量参数确定该主题的研究趋势。还确定了微藻生物量利用方面的技术进展。此外，还可以确定不同国家之间的不同合作网络，这些网络显示出通过微藻来降低 CO 浓度的研究具有互动性。
