Hydrogen evolution on Ni/WC composite coatings
Abstract
The catalytic activity for the hydrogen evolution reaction (HER) of Ni/WC composites obtained by electrochemical
deposition of nickel from a conventional Watt’s bath, using two different ways of depositing the WC particles, was
investigated. All the composite coatings exhibited electrocatalytic activity for the HER larger than that of pure Ni in
both alkaline and acid solution. The activity increased with increasing content of WC in the coating and, in the
pulsed current regime, with increasing frequency of pulsation. In addition, coatings with smaller particles incorporated
exhibited higher activity than those with larger particles. At a constant potential, an order of magnitude
higher current densities were obtained in some cases.
