Abstract

The effects of hot alkaline treatment and Fe₂O₃ modification of hydrogen storage alloy on the electrocatalytic activity for oxidation of borohydride have been investigated using linear sweep voltammetry. The performance of borohydride electrochemical oxidation was significantly influenced by the hot alkaline treatment and Fe₂O₃ modification of the hydrogen storage alloy. The results showed that the current density of the Fe₂O₃-modified hot alkaline-treated hydrogen storage alloy electrode containing 5 wt% Fe₂O₃ reached 125 mA•cm^-2 in 0.10 mol•L^-1 NaBH₄ and 2 mol•L^-1 NaOH solution at -0.55 V vs. saturated Ag/AgCl, KCl electrode.
