Abstract
A hollow mesoporous trimetallic NiFeCr hydroxide electrode is prepared via a four-step procedure involving the fast electrodeposition of an Ni/Cr/Fe alloy onto a nickel foam substrate, followed by dealloying, oxidation, and activation. The title electrode shows an ultralow onset overpotential of 210 mV for the oxygen evolution reaction and a high specific capacity of 1768 F g-1 as a redox capacitor.
