Selective hydrogenation of carbon dioxide (CO₂) into value-added chemicals has aroused great interest. The chemical inertness of CO₂ and diverse reaction pathways usually require the construction of enabled catalysts. To date, cobalt (Co) catalysts characteristic of metallic and/or divalent Co components show great potential for CO₂ hydrogenation. To better regulate the CO₂ hydrogenation, it is necessary to summarize the current progress of cobalt catalysts for selective hydrogenation of CO₂. In this Perspective, first, hydrogenation of CO₂ into methane over metallic Co sites is introduced. Second, hydrogenation of CO₂ into methanol and C₂₊ alcohols is discussed by constructing mixed-valent cobalt sites. Third, hydrogenation of CO₂ into light olefins and C₅₊ liquid fuels over cobalt-containing hybrid catalysts is introduced. Fourth, the reaction paths for selective hydrogenation of CO₂ over cobalt catalysts are illustrated. Finally, the current challenges and prospects of cobalt-based nanocatalysts for hydrogenation of CO₂ are proposed.

钴催化剂使 CO2 选择性加氢生成多种产品：最新进展和前景

将二氧化碳 (CO ₂ )选择性氢化成具有附加值的化学品引起了人们极大的兴趣。CO ₂的化学惰性和不同的反应途径通常需要构建启用的催化剂。迄今为止，具有金属和/或二价 Co 组分特征的钴 (Co) 催化剂显示出 CO ₂加氢的巨大潜力。为了更好地调控CO ₂加氢，有必要总结一下钴催化剂在CO ₂选择性加氢方面的研究进展。在该观点中，首先介绍了在金属 Co 位点上将CO ₂加氢成甲烷。二、CO ₂加氢生成甲醇和C ₂₊通过构建混合价钴位点来讨论醇。第三，引入了在含钴混合催化剂_上将CO ₂加氢成轻质烯烃和C ₅₊液体燃料。第四，阐述了CO ₂在钴催化剂上选择性加氢的反应路径。最后，提出了钴基纳米催化剂用于 CO ₂加氢的当前挑战和前景。
