Electrocatalytic carbon dioxide (CO2) reduction reaction (CO2RR) has offered a sustainable approach in converting an anthropogenic CO2 source to chemicals and fuels promote neutral. However, it remains challenging prepare high-performance catalysts for efficient selective electroreduction, especially toward the high-vaule multicarbon products. Here we report facile synthesis of four kinds nearly monodispersed CuTrz (HTrz = 1H,1,2,4-triazole) metal–organic framework (MOF) nanostructures with different sizes by controlling kinetics. Significantly, small demonstrate much superior CO2RR performance over large counterparts production neutral electrolytes, optimized Faradaic efficiency 55.4% 81.8% ethylene products, respectively. Detailed structural characterizations reveal that are polycrystalline rich grain boundaries, while ones single crystalline. This work highlights importance simultaneous defect size control MOFs boosting their production.

ABSTRACT Both the catalyst and electrolyte strongly impact performance of CO2 electrolysis. Despite substantial progress in catalysts, it remains highly challenging to tailor compositions understand their functions at interface. Here, we report that ethylenediaminetetraacetic acid (EDTA) its analogs, featuring strong Lewis acid-base interaction with metal cations, are selected as additives reshape catalyst-electrolyte interface for promoting Mechanistic studies reveal EDTA molecules dynamically assembled toward regions response bias potential due EDTA4–-K+. As a result, original hydrogen-bond network among interfacial H2O is disrupted, gap layer electrified established. The EDTA-reshaped K+ solvation structure promotes protonation *CO2 *COOH suppressing *H2O dissociation *H, thereby boosting co-electrolysis carbon-based products. In particular, when 5 mM added into electrolytes, Faradaic efficiency CO on commercial Ag nanoparticle increased from 57.0% 90.0% an industry-relevant current density 500 mA cm−2. More importantly, Lewis-base ligand-reshaped allows range catalysts (Ag, Zn, Pd, Bi, Sn, Cu) deliver substantially selectivity products both H-type flow-type electrolysis cells.
