Reducing carbon dioxide emission and converting carbon dioxide from the air have always been a hot topic for researchers. Carbon dioxide is an ideal raw material for synthesizing organic compounds because of its good physical properties such as non-toxicity, abundance and easy availability. In recent years, hydrosilylation reaction has become an effective method to convert carbon dioxide into formate, formaldehyde, methanol, methane and other valuable chemical products under moderate conditions, which greatly promotes the conversion and utilization of carbon dioxide. The research progress on the design, synthesis and catalytic performance of catalytic systems used to catalyze the hydrosilylation for reduction of carbon dioxide is summarized and discussed. The reaction mechanism of hydrosilylation reduction of carbon dioxide is discussed, and the advantages and disadvantages of various catalyst systems are also analyzed. At last, the future research directions in this field are prospected.

CO 2 与氢 硅烷在不同条件下反应可生成不同产物, 如硅烷基甲酸 酯(HCOOSiR 3 )、双(硅烷基)缩醛[H 2 C(OSiR 3 ) 2 ]、甲氧基 硅烷(R 3 SiOCH 3 )和甲烷(CH 4 ) (Scheme 1) [1] . CO 2 还原得 到的产物甲酸可继续在氢硅烷作用下与胺进行甲酰化
