Synthesis of helical carbon nanotubes wrapped around Ni2P1−xOx nanoparticle-incorporated carbon nanoribbons as an efficient electrocatalyst for the hydrogen evolution reaction†

Abstract

Helical CNTs wrapped around Ni₂P_1−xO_x 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.
