Nickel cobaltite (NiCo2O4) nanowires were successfully grown on the surface of carbon fiber via hydrothermal treatment, followed by annealing. After 2 h, SEM revealed the formation of NiCo2O4 nanowire arrays on the surface of the carbon fiber paper. With increasing hydrothermal time from 2 to 12 h, the NiCo2O4 nanowires also self-assembled into urchin-like morphologies. When used as catalysts for hydrogen evolution reaction, the NiCo2O4 nanowires exhibit an onset potential for the cathodic current at-0.13 V vs. Ag/AgCl in 0.1 M KOH.

Effect Of Surface

The RGO-modified Ni electrode exhibited outstanding activity towards HER. DFT calculations indicate that H atoms, formed upon H2O discharge on Ni, spill onto the RGO, enabling continuous clearance of Ni-active sites.

One Step

The composites of sulphide and reduced graphene oxide (NiS/MoS2-rGO) were synthesized through a facile solvent-assisted hydrothermal method. The introduction of NiS was paramount not only in enhancing the conductivity of whole catalysts but also in modulating the layer structures of MoS2 with additional active sites. Moreover, the NiS and rGO functioned together in controlling the morphology of as-prepared composites, resulting in uniformly distributed NiS/MoS2 nanosheets perpendicular to rGO scaffold. This further contributed to the excellent hydrogen evolution performance of the composites with a small onset overpotential of 80[Formula: see text]mV and Tafel slope as low as 65[Formula: see text]mV/decade.
