Ru–Fe4C nanoparticles loaded on N-doped carbon nanofibers as self-supporting high-efficiency hydrogen evolution electrocatalysts

“…3(f), the high-resolution C 1s spectrum and the subpeaks at binding energies of 284.8 eV, 285.6 eV and 289.6 eV correspond to CC/C–C, CN and CO, respectively. 29,30 For the N 1s spectrum, the binding energies of 398.2 eV, 400.0 eV, 401.05 eV and 403.1 eV belong to pyridine nitrogen, pyrrole nitrogen, graphite nitrogen and nitrogen oxide, respectively (Fig. 3(g)).…”

Anchoring FeRu Bimetallic Nanoparticles on N-Doped Graphene Nanosheets for Efficient Overall Water Splitting

“…Besides, Fe 3 C nanoparticles have a strong interaction with RuO 2 due to their high permeability, which is beneficial to the dispersion of RuO 2 on the surface of carbon substrate, exposing more active sites . Carbon materials such as activated carbons, carbon nanofibers, carbon nanotubes, graphene, , and graphdiyne offer versatile substrates for metal and metal-oxide nanoparticles. , Among them, N-doped porous graphene was selected as the support because of its hierarchical network, large specific surface area, rich pores, excellent electrical conductivity, and chemical stability. Moreover, since N can change the charge distribution of graphene greatly due to its large electronegativity, it promotes the adsorption properties and enhances electron transportation.…”
