The Cover Feature illustrates electrochemically treated mild steel (cathodic and electrodeposition of Ni(OH) 2 ) as a substrate/catalyst/host for the oxygen evolution reaction (OER) in alkaline media and the corresponding catalytic activities. The cathodic treatment of the mild steel substrate forms fine and rough Fe(OH) 2 /FeOOH, which benefits the subsequent electrodeposition of Ni(OH) 2 , resulting in the heterostructure formation of catalytically active Fe(OH) 2 /FeOOH/Ni(OH) 2 . The background image depicts the HRTEM elemental distribution of Fe and Ni. This study suggests a viable mild steel surface treatment and choice of substrate, metal oxide, and hydroxide interactive materials for various electrochemical applications.
