摘要

•Single-atom Cu/MnO2 is a low-cost and high-performance catalysts for CO oxidation.•Atomically dispersed Cu is anchored on the MnO2 support via a simple hydrothermal method.•The SMSI between the single atom Cu and the support can effectively suppress the aggregation of Cu single atoms.•The surface lattice oxygen was activated by the introduction of Cu greatly promoted the CO catalytic performance.
