Key Points

The aim is to determine how different facet ratios of CuO affect selectivity for C2+ products during CO2 electroreduction.
Fabricated three CuO catalysts with varying (111) to (11-1) facet ratios.
Conducted CO2 electroreduction experiments with the different catalysts.
CuO-2 catalyst demonstrated the highest selectivity for C2+ products.
Significant differences in product distributions were observed among the three catalysts.

Abstract

Three CuO catalysts (denoted as CuO-1, CuO-2 and CuO-3) with different ( 111) to (11-1) facet ratios, were fabricated for CO 2 electroreduction. Among them, the CuO-2 with a balanced (111)/(11-1)...
