Carbon capture and utilization technology is one of the medium-term technology options to reduce CO₂ emissions while producing value-added fuels and chemical products. The integrated CO₂ capture and hydrogenation process is an encouraging replacement to the conventional decoupled CO₂ capture and hydrogenation process, which allows direct utilization of captured CO₂ thus eliminating the energy-intensive CO₂ desorption and compression steps in the typical carbon capture and storage (CCS) process. The hydrogenation of captured CO₂ in amine/alkali hydroxide solvents is the key step to attain the integrated CO₂ capture and hydrogenation process. Considering the lack of timely review on the topic of hydrogenation of amine/alkali hydroxide solvent captured CO₂ to formate in the presence of heterogeneous catalysts, a summary of such process with different capturing solvents and heterogeneous catalyst were critically summarized and briefly reviewed in the current paper. The main goal of this review is to provide fundamental insights and guidance for the future design of heterogeneous catalysts for the hydrogenation of captured CO₂ in amine/alkali metal hydroxide-based solvents. Future research directions to advance the process of hydrogenation of captured CO₂ were also recommended. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

胺/碱金属氢氧化物溶剂加氢反应的多相催化剂捕获 CO2 生成甲酸盐：综述

碳捕获和利用技术是在生产高附加值燃料和化学产品的同时减少 CO ₂排放的中期技术选择之一。集成的 CO ₂捕获和加氢工艺是对传统解耦 CO ₂捕获和加氢工艺的令人鼓舞的替代，它允许直接利用捕获的 CO ₂从而消除典型碳捕获和储存中的能源密集型 CO ₂解吸和压缩步骤(CCS) 过程。在胺/碱金属氢氧化物溶剂中对捕获的 CO ₂进行加氢是获得综合 CO ₂的关键步骤捕获和加氢过程。考虑到在多相催化剂存在下胺/碱金属氢氧化物溶剂捕集CO ₂加氢制甲酸这一课题缺乏及时综述，本文对不同捕集溶剂和非均相催化剂的此类工艺进行了总结总结和简要综述。纸。本综述的主要目标是为未来设计用于在胺/碱金属氢氧化物基溶剂中氢化捕获的 CO ₂的多相催化剂提供基本见解和指导。还推荐了推进捕获的 CO ₂加氢过程的未来研究方向。© 2021 化学工业协会和 John Wiley & Sons, Ltd.
