Abstract High‐performance catalysts sufficient to significantly reduce the energy barrier of water activation are crucial in facilitating reactions that restricted by dissociation. Herein we present a Cu−Co double‐atom catalyst (CuCo‐DAC), which possesses uniform and well‐defined CuCoN 6 (OH) structure, works together promote silane oxidation. The achieves superior catalytic performance far exceeding single‐atom (SACs). Various functional silanes converted into silanols with up 98 % yield 99 selectivity. Kinetic studies show oxidation CuCo‐DAC is lower than Cu (Cu‐SAC) Co (Co‐SAC). Theoretical calculations demonstrate two different reaction pathways where splitting rate‐determining step it accelerated CuCo‐DAC, whereas H 2 formation key for its counterpart.
