Abstract

A nitrogen-doped carbon-supported CuNi bimetallic nanocluster catalyst (CuNi–NC) was first synthesized via a facile ZIF-derived method. With a synergistic effect between Cu and Ni, the catalyst exhibited a maximum FE_CO of 96.3%. FE_CO is higher than 90% in a broad potential range of 600 mV, which was ascribed to the controllable pore size distribution. Density functional theory further demonstrated the preferred formation of *COOH in the catalytic process.
