英文摘要	Two-dimensional (2D) layered double hydroxide (LDH) is a good alternative to precious metals in terms of oxygen evolution electrocatalysis. The doping of various elements into LDH has been widely investigated in order to further minimize the oxygen evolution overpotential. Herein, by using the cation exchange method, we design and construct a Fe-doped Ni−Al LDH nanoplatelets (NAF LDH-25). Fe3+ enter the nickel and aluminum vacancies smoothly as a result of the dual action of corrosion and cation exchange, and iron ion activity is optimized. Meanwhile, strong interaction of Ni and Fe, effect of Al on electronic structure and the structural advantages of two-dimensional nanoplatelets, as a result, the as-prepared NAF LDH-25 exhibits extremely low overpotential (288 mV) at high current density of 100 mA cm−2. The NAF LDH-25 also showed excellent stability in the 72 h chronopotentiometry test. Therefore, cation exchange strategy provides a new option for the preparation of practical OER catalysts. © 2022 Wiley-VCH GmbH.
