将二氧化碳(CO2)转化为高附加值化学品或燃料是实现碳循环的理想途径. 作为C1化学的重要组成部分, 二氧化碳的还原转化研究一直备受化学家们关注. 在过渡金属催化条件下, 利用氢气、硼烷或硅烷(E—H, E=H、B或Si)作为还原剂, 可以将CO2还原到甲酸、甲醛、甲醇等各种有机分子. 特别是, 基于廉价金属催化CO2选择性还原转化已成为该领域的一个重要研究方向. 从反应机理和反应选择性出发, 对均相铁催化CO2的E—H化还原研究进展进行综述.

Carbon dioxide (CO2) serves as a sustainable carbon source for building biomass, fossil fuels, and organic chemicals. Converting CO2 into value-added chemicals or fuels is an ideal approach to achieve carbon cycling. The reduction and conversion of CO2, a pivotal aspect of C1 chemistry, have long been a subject of intense research interest. Previous studies have demonstrated that through transition metal catalysis, hydrogen, boranes, and silanes (E—H, E=H, B or Si) act as effective reducing agents to transform CO2 into a range of C1 chemicals, such as formate, formaldehyde, and methanol. Over the past decade, research focus in this field has shifted towards utilizing cost-effective metals as catalysts for selective CO2 reduction. A comprehensive review of homogeneous iron-catalyzed CO2 reduction using E—H is presented, emphasizing reaction mechanisms and selectivity.
