A “Trojan horse” strategy towards robust Co–N4 active sites accommodated in micropore defect-rich carbon nanosheets for boosting selective hydrogenation of nitroarenes

Through a novel “Trojan horse” strategy, a reinforced single-atom Co catalyst with robust Co–N 4 active sites accommodated in micropore defect-rich carbon nanosheets was rationally fabricated for boosting selective hydrogenation of nitroarenes.
