Improving the Electrocatalytic Activity of a Core/Shell NiCo–ZIF@PBA Catalyst by Co–O–Fe Bridge Bonds for Water Oxidation

In response to the limitations of slow reaction kinetics and elevated overpotentials in the OER, a novel core-shell structured electrocatalyst, termed NiCo-ZIF-67@Fe-Co-Ni-PBA or NiCo-ZIF@PBA, has been developed. This material demonstrates exceptional catalytic performance, exhibiting a minimal overpotential of approximately 188 mV at 10 mA cm
