Abstract

Charge-redistributed Co₃O₄/Fe_0.3Co_0.7P heterointerfaces are designed for effective electrocatalytic urea oxidation in alkaline medium, delivering excellent performance with only 1.41 V vs. RHE at 100 mA cm⁻², low Tafel slope of 74 mV dec⁻¹ and 36-h robust stability. The fine regulation of charge redistribution through heterointerfaces provides an effective strategy to design highly efficient electrocatalysts.
