Herein, N,S-codoped carbon materials embedded with ultrafine and well-distributed Co nanoparticles (1.14 wt % Co) were prepared through pyrolysis of the hybrids SNW-1 Co(Ac)2 coated glucose. It was observed by TEM XRD that (NPs) entrapped in doped shells uniformly. The glucose coating presented a significant impact on size distribution NPs modes heteroatoms, especially S species. catalyst displayed outstanding activity for catalytic transfer hydrogenation (CTH) formic acid under base-free system. Encouragingly, diverse secondary amines produced excellent yields domino reaction reductive amination. Remarkably, showed good durability harsh conditions no loss both selectivity 5 runs. This attributed to protection constructed N,S dual-doped shells. Hence, we offer an alternative strategy construction trapped transition metal, which can be further applied various processes.
