The anodic oxidation of hydrogen on sodium tungsten bronzes

Abstract

The anodic oxidation of hydrogen has been studied on Na_0.72WO₃ electrodes in H₂SO₄ solutions over the potential range 0.35-1.34 V (s.h.e.). Only one mechanism, which involves the rate-determining dissociation (H_2(ad)→2H_(ad)) with Temkin adsorption of H₂, has been found to be consistent with the experimental data.
