Abstract

Abstract Electrochemical CO2 reduction to valuable multi‐carbon (C2+) products is attractive but with poor selectivity and activity due to the low‐efficient CC coupling. Herein, a lithium vacancy‐tuned Li2CuO2 with square‐planar [CuO4] layers is developed via an electrochemical delithiation strategy. Density functional theory calculations reveal that the lithium vacancies (VLi) lead to a shorter distance between adjacent [CuO4] layers and reduce the coordination number of Li+ around each Cu, featuring with a lower energy barrier for COCO coupling than pristine Li2CuO2 without VLi. With the VLi percentage of ≈1.6%, the Li2−xCuO2 catalyst exhibits a high Faradaic efficiency of 90.6 ± 7.6% for C2+ at −0.85 V versus reversible hydrogen electrode without iR correction, and an outstanding partial current density of −706 ± 32 mA cm−2. This work suggests an attractive approach to create controllable alkali metal vacancy‐tuned Cu catalytic sites toward C2+ products in electrochemical CO2 reduction.
