Non-metallic element modulation of Co 3 O 4 /NiFe-LDH hetero-junction electrocatalysts for efficient oxygen evolution reaction

The doping of non-metallic boron generates oxygen vacancies and alters electron redistribution at the heterostructure interface. In an alkaline environment, the prepared B-Co₃O₄@NiFe-LDH electrocatalyst displays a low OER overpotential of 115 mV at 10 mA cm^-2, demonstrating superior OER activity.
