Abstract
Abstract Copper is a key metal for carbon dioxide (CO 2 ) reduction reaction, which can reduce CO 2 to value‐added products. The core‐shell structure can effectively promote the C−C coupling process due to its strong synergistic effect originated from its unique electronic structure and interface environment. Therefore, the combination of copper and core‐shell structure to design an efficient Cu‐based core‐shell structure catalyst is of great significance for electrocatalytic CO 2 reduction (CO 2 RR). In this review, we first briefly summarize the basic principle of CO 2 RR. In addition, we outline the advantages of core‐shell structure for catalysis. Then, we review the recent research progresses of Cu‐based core‐shell structures for the selective reduction of multi‐carbon (C 2+ ) products. In the end, the challenges of using core‐shell catalyst for CO 2 RR are described, and the future development of this field is prospected.
