摘要：

In recent years, the influence of structural properties such as valence, facet and micromorphology on the catalytic performance of Cu-based catalysts has been extensively studied, and highly selective electrochemical reduction of CO2 to high value-added multi-carbon (C2+) products over Cu-based catalysts has achieved great progress. This review provides an overview of the research progress in structured Cu-based catalysts for electrochemical reduction of CO2 to C2+ products in the past five years, and analyzes the structure-activity relationship among the catalytic activity and reaction selectivity and the presence of mixed valence states, high-active facets and rich grain boundaries on the catalyst surface, as well as the structures with abundant confine spaces such as nanowire arrays, nanodendrites and nanoporous structures. The new trend in CO2 electrochemical reduction is further proposed, that is, to take full advantage of the synergistic effect of various structural factors, to in situ prepare nanoporous Cu-based catalysts with mixed valence states and rich grain boundaries, and to apply flow cell to efficiently and continuously reduce CO2 to C2+ products. © 2021, Chemical Industry Press Co., Ltd.
