Abstract
Abstract Single atom catalysts (SACs) have been widely studied in the field of CO 2 electroreduction, but industrial‐level current density and near‐unity product selectivity are still difficult to achieve. Herein, a diatomic site catalysts (DASCs) consisting of Co‐Cu hetero‐diatomic pairs is synthesized. The CoCu DASC exhibits excellent selectivity with the maximum CO Faradaic efficiency of 99.1 %. The CO selectivity can maintain above 95 % over a wide current density range from 100 mA cm −2 to 500 mA cm −2 . The maximum CO partial current density can reach to 483 mA cm −2 in flow cell, far exceed industrial‐level current density requirements (>200 mA cm −2 ). Theoretical calculation reveals that the…
