Abstract It is highly desired but still challenging to engineer single‐atom catalysts featuring an M–N–C configuration for efficient catalytic hydrogenation. Herein, Ni nanoparticles (Ni NPs) modified Ni–N–C (termed as Ni 1+NPs /NSPC) were fabricated to demonstrate the feasibility of enhancing the catalytic hydrogenation performance of M–N–C by introducing metallic NPs sites. Ni NPs sites and Ni 1 sites displayed a synergistic effect: Ni NPs promote the dissociation of H 2 in a homolytic manner with a lower barrier energy than the heterolytic one that occurred on Ni 1 sites, whereas Ni 1 could burden the activation of substrates. The active H atoms generated at Ni NPs migrate to Ni 1 sites to complete hydrogenation. Consequently, Ni 1+NPs /NSPC catalysts were empowered with excellent hydrogenation performance; they can be applied to a series of hydrogenation substrates (e.g., nitro compounds, furfural, quinine, and cyanophenyl) affording high conversion (95.1%–99.9%) and selectivity (96.8%–99.9%).
