Abstract: • Two-dimensional dual-Copper sites metal-organic framework with strong intra/inter-layer interactions. • Three-dimensional charge transfer pathway constructed by dense coplanar stacking and interlayer π-π interactions. • Three-dimensional charge transfer pathway accelerates charge transport and improves the catalytic performance. • Guiding models for the design of two-dimensional metal-organic framework-based electrocatalysts. The electrochemical reduction of CO 2 into multi-carbon products holds great promise to simultaneously reduce the carbon emission and generate high value-added products. However, the high kinetic barrier in the process of C-C coupling presents a significant challenge for it. In this study, referring to the structural advantages of two-dimensional (2D) conductive MOFs, we show an example of coplanar 2D Cu-MOF (denoted as Cu(4-pt)) with rich dual-Cu sites as a structural model for electrocatalytic reduction of CO 2. In Cu(4-pt), each Cu(I) is connected by coplanar 4-pt ligand to form a coplanar 2D layer stacked in an ABAB mode, giving ultrashort Cu...Cu distance (3.21 Å) between adjacent layers. Theoretical simulation verifies the special interlayer interactions and 3D charge transfer pathways within this unique coplanar stacking structure. Experimental results show that Cu(4-pt) has about 4 times C 2 H 4 reduction ability compared with Cu(tz) with the same type of binuclear Cu site layered stacking structure. The results reveal that the clear dual Cu sites and interlayer interactions formed by coplanar stacking greatly reduce the reaction energy barrier and effectively promote the C-C coupling to produce C 2 H 4. This work provides a clear structural model for the design of efficient Cu-MOF-based CO 2 reduction catalysts. [ABSTRACT FROM AUTHOR]
