Abstract
In this communication, hematite nanorods array is developed on carbon cloth (α-Fe2O3 NA/CC) as a novel anode for oxygen evolution reaction in alkaline electrolytes. This integrated 3D electrode exhibits an onset overpotential of 330 mV and a Tafel slope of 52 mV decâ 1 and its catalytic activity is superior over preformed α-Fe2O3 nanorods immobilized on CC using a polymer binder. Furthermore, this electrode affords current density of 10 mA cmâ 2 at an overpotential of 420 mV and is capable of maintaining its catalytic activity for at least 10 h.
