Abstract
Electrocatalytic CO
2
reduction reaction (CO
2
RR) provides an effective approach for converting CO
2
into high value-added chemicals and fuels. In CO
2
RR research
precise modulation of the catalyst’s composition and structure is crucial for achieving high product selectivity. Cu is currently the most effective active metal component for driving CO
2
RR toward C
2+
products. To gain a comprehensive understanding of the factors governing C
2+
product formation on Cu-based catalysts
studies about CO
2
RR to C
2+
products have been comprehensively analyzed and summarized. Starting from the adsorption mechanisms of CO
2
on Cu-based catalyst surfaces
the effects of critical parameters such as Cu crystal facets
low-nuclearity Cu atomic clusters
Cu species valence states
and catalyst morphologies on CO
2
RR performance were thoroughly explored
with emphasis on their roles in regulating C
2+
products selectivity. Furthermore
current challenges and future research directions for C
2+
products by CO
2
RR were outlined
aiming to provide guidance for the rational design of high-efficiency catalysts for CO
2
RR.
