Abstract
Abstract Atomic-level coordination engineering is an efficient strategy for tuning the catalytic performance of single-atom catalysts (SACs). However, their rational design has so far been plagued by the lack of a universal correlation between the coordination symmetry and catalytic properties. Herein, we synthesised planar-symmetry-broken CuN 3 (PSB-CuN 3 ) SACs through microwave heating for electrocatalytic CO 2 reduction. Remarkably, the as-prepared catalysts exhibited a selectivity of 94.3% towards formate at −0.73 V vs. RHE, surpassing the symmetrical CuN 4 catalyst (72.4% at −0.93 V vs. RHE). In a flow cell equipped with a PSB-CuN 3 electrode, over 90% formate selectivity was maintained at an average…
