Spinel‐type NiFe 2 O 4 with oxygen vacancies was prepared via a simple hydrothermal method followed by mild reduction under hydrogen flow and used as a catalyst for the oxygen evolution reaction (OER). The oxygen‐deficient spinel‐type oxide nanoparticles exhibited excellent electrocatalytic activity and long‐term durability for the OER in alkaline medium. The outstanding electrochemical performance was attributed to the improved physicochemical properties by induced oxygen vacancies.
