Abstract
Abstract NiOOH is considered as the most active intermediate during electrochemical oxidation reaction, however, it is hard to directly synthesize due to high oxidation energy. Herein, theoretical calculations predict that α‐FeOOH enables a decline in formation energy and an improvement in stabilization of NiOOH in NiFe‐based layered double hydroxide (LDH). Inspiringly, a composite composed of α‐FeOOH and LDH is well‐designed and successfully fabricated in hydrothermal treatment by adding extra Fe 3+ resource, and stable NiOOH is obtained by the following electro‐oxidation method. Benefiting from strong electron‐capturing capability of α‐FeOOH, it efficiently promotes charge redistribution around the Ni/Fe…
