Abstract:

Ni(OH)2 nanosheet arrays on carbon cloth[Ni(OH)2 NAs/CC] were synthesised via hydrothermal treatment. Then Ni3N nanosheet arrays on carbon cloth(Ni3N NAs/CC) were prepared through the nitridation of corresponding Ni(OH)2 NAs/CC precursor with NH3, thus polymer binder free three dimensional self-supporting electrode was established. The structure and morphology of the composite electrode materials were investigated by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM) and transmission electron microscopy(TEM) analyses. The results indicate that the porosity, roughness and electrochemical effective area of Ni3N NAs/CC electrode surface are increased. The activities for the oxygen evolution reaction(OER) of the Ni3N NAs/CC were explained by recording linear scanning voltammograms and Tafel plots, the results indicate that the activity for OER is effectively increased and the overpotential for oxygen evolution could be lowered by approximately 280 mV. In the meantime, Ni3N NAs/CC electrode exhibited good durability.
