Synthesis of helical carbon nanotube wrapped on Ni2P1-xOx nanoparticles-incorporated carbon nanoribbon as an efficient electrocatalyst for hydrogen evolution reaction

Helical CNTs wrapped around Ni2P1-xOx nanoparticle-incorporated carbon nanoribbons were prepared by nickel-catalysis and phosphatization. The obtained highly conductive nanocomposite with an active Ni-O-P structure and appropriate Gibbs free energy for adsorbing protons was applied as an advanced electrocatalyst for the HER and delivered comparable electrocatalytic performance to commercial Pt/C in acidic solution.
