| Summary: | Highlights Highly crystalline 2D metal hydrogen-bonded organic frameworks (2D-M-HOFs) including 2D-Cu-HOF and 2D-Ni-HOF were designed and synthesized. The 2D-M-HOF with flexible ligands leads to the formation of the self-adaption interlayered sites, which facilitate the C–C couple and overcome the limitations of the coadsorption of multiple intermediates in the electrocatalytic CO2 reduction reaction. The undulated 2D-Cu-HOF exhibits outstanding activity and selectivity for electrocatalytic reduction of CO2 to C2 products with a total Faradaic efficiency of 82.1% (48.2% for C2H5OH and 33.9% for C2H4) at −1.2 V vs. RHE. |
