Spinel-type NiFe2O4 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. More information can be found in the Full Paper by Sung-Hyeon Baeck et al.
