单原子催化剂在二氧化碳还原转化中的应用及展望

Application of single-atom catalysts in carbon dioxide reduction

CO_2是一种储量丰富、廉价易得的碳资源,借助可再生能源的CO_2资源化利用是实现可持续发展战略的有效途径.近年来,单原子催化剂因其独特的结构特性被广泛应用,已成为连接多相与均相催化的桥梁.本文综述了单原子催化剂在CO_2催化还原转化中的应用,基于CO_2在多相纳米催化与均相催化体系中的反应特点,对单原子催化剂的设计及不同外场环境下活性中心电子结构的调控机制进行探讨,进而展望了单原子催化剂在CO_2资源化利用中的发展前景与挑战.

As an abundant and inexpensive C1 resource, CO2 transformation by renewable energy has attracted much interest, and become a most promising strategy for sustainable development. Meanwhile, the single-atom catalyst, with its unique structure and electronic properties, has been widely used and acted as a bridge between hetero-and homogeneous catalysis. In this review, we outlined the recent advances on single-atom catalysts toward the catalytic reduction of CO2 under different external environment conditions, including the design of single-atom catalysts, the catalytic behavior of single atoms in CO2 conversion, as well as the challenges and prospect of such novel catalysts in the fields of CO2 reduction.
