Abstract

A dual in situ electrochemical activation strategy is proposed to synergistically boost the activity and stability of NiFe hydroxides. Stainless-steel mesh activation steadily supplies Fe ions, improving the durability by 6 and 4 times in alkaline and neutral media, respectively. The modulation of Ni and Fe valences by releasing high-valence Cr, together with the Lewis acid sites, leads to a significant improvement in the NiFe hydroxide's intrinsic activity.
