Highly active hollow mesoporous NiFeCr hydroxide as an electrode material for the oxygen evolution reaction and a redox capacitor

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...

Description
Summary: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. A hollow mesoporous structure NiFeCr hydroxide electrode (HMS-NiFeCrO) was prepared, which 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.
