We present an effective strategy for developing the dispersing strong-binding metal In on surface of weak-binding Zn, which modulates binding energy reaction intermediates and further facilitates efficient conversion CO2 to formate. The In-Zn interface (In-Zn2) benefits from formation active sites through favorable orbital interactions, leading a Faradaic efficiency 82.7% formate partial current density 12.39 mA cm-2, along with stable performance over 15 h at -1.0 V versus reversible hydrogen electrode.

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(44)

Опубликована: Июль 24, 2024

Abstract 2D functional porous frameworks offer a platform for studying the structure–activity relationships during electrocatalytic CO 2 reduction reaction (CO RR). Yet challenges still exist to breakthrough key limitations on site configuration (typical M−O 4 or M−N units) and product selectivity (common ‐to‐CO conversion). Herein, novel metal–organic framework (MOF) with planar asymmetric N/O mixed coordinated Cu−N 1 O 3 unit is constructed, labeled as BIT‐119. When applied RR, BIT‐119 could reach ‐to‐C conversion C partial current density ranging from 36.9 165.0 mA cm −2 in flow cell. Compared typical symmetric Cu−O units, units lead re‐distribution of local electron structure, regulating adsorption strength several adsorbates following catalytic selectivity. From experimental theoretical analyses, sites simultaneously couple atop‐type (on Cu site) bridge‐type *C species conversion. This work broadens feasible C−C coupling mechanism frameworks.
