  text: High-entropy materials offer numerous advantages as catalysts, including a
    flexible composition to tune the catalytic activity and selectivity and a large
    variety of adsorption/reaction sites for multistep or multiple reactions. Herein,
    we report on the synthesis, properties, and electrocatalytic performance of an
    amorphous high-entropy boride based on abundant transition metals, CoFeNiMnZnB.
    This metal boride provides excellent performance toward the oxygen evolution reaction
    (OER), including a low overpotential of 261 mV at 10 mA cm–2, a reduced Tafel
    slope of 56.8 mV dec–1, and very high stability. The outstanding OER performance
    of CoFeNiMnZnB is attributed to the synergistic interactions between the different
    metals, the leaching of Zn ions, the generation of oxygen vacancies, and the in
    situ formation of an amorphous oxyhydroxide at the CoFeNiMnZnB surface during
    the OER.
