Easy Conversion Perovskite Fluorides KCo1-xFexF3 for Efficient Oxygen Evolution Reaction Herein, we report an easily oxidized Co-Fe perovskite fluoride as an efficient catalyst for oxygen evolution reaction (OER). In-situ Raman spectroscopy showed that the presence of F promotes the reconstruction to form highly active (Co3+Fe3+)OOH, and the current density of 10 mA cm-2 can be achieved at the overpotential of only 118 mV in 1 M KOH aqueous solution.
