Abstract
Abstract Highly effective electrocatalysts promoting CO 2 reduction reaction (CO 2 RR) is extremely desirable to produce value-added chemicals/fuels while addressing current environmental challenges. Herein, we develop a layer-stacked, bimetallic two-dimensional conjugated metal-organic framework (2D c -MOF) with copper-phthalocyanine as ligand (CuN 4 ) and zinc-bis(dihydroxy) complex (ZnO 4 ) as linkage (PcCu-O 8 -Zn). The PcCu-O 8 -Zn exhibits high CO selectivity of 88%, turnover frequency of 0.39 s −1 and long-term durability (>10 h), surpassing thus by far reported MOF-based electrocatalysts. The molar H 2 /CO ratio (1:7 to 4:1) can be tuned by varying metal centers and applied potential, making 2D c…
