Abstract
- 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.
