Charge-redistributed Co3O4/Fe0.3Co0.7P heterointerfaces for efficient electrocatalytic urea oxidation†
Abstract
Charge-redistributed Co3O4/Fe0.3Co0.7P 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.
