Synthesis and characterization of cobalt-supported catalysts on modified magnetic nanoparticle: Green and highly efficient heterogeneous nanocatalyst for selective oxidation of ethylbenzene, cyclohexene and oximes with molecular oxygen.

In this study, a new supported cobalt nanocatalyst has been described. The FeO magnetic nanoparticles (FeO MNPs) modified by SiO/aminopropyl trimethoxy silane/cyanuric chloride (FeO@SiO-APTMS/CC) utilized for anchoring metformin-cobalt complex (FeO Ms@SiO-APTMS/CC/Met@Co(II)). The structure of novel complex well defined by elemental analysis, ICP, AAS, BET, FT-IR, EDX, SEM, TEM, DLS, XRD, TG-DTG, VSM and XPS.
