This study was aimed at elucidating the role of carboneous component in Co–carbon-containing catalysts for hydrogenation organic compounds. A Co-C/SiO2 catalyst synthesized via pyrolysis a Co(II) complex with 1,2-diaminobenzene on silica and subsequently irradiated 2.3 MeV electrons, producing Co-C/SiO2*. comprehensive characterization using XRD, TEM, IR, Raman spectroscopy indicated minimal structural changes cobalt nanoparticles materials. However, analysis revealed slight decrease defect content upon irradiation, which could occur due to healing. The catalytic tests, including 26 compounds, demonstrated an enhanced performance 17 cases. improvement attributed modification material. It be concluded that components Co-C composites contributed their performance, probably by modifying electronic structure Co nanoparticles. In turn, results provide arguments against supposition occurs defects
