Abstract

Commercial carbon fiber cloth treated at 450 °C in air (CFC-450) possesses low C[double bond, length as m-dash]O content, exhibiting outstanding oxygen evolution activity in 1.0 M KOH electrolyte with an overpotential of 224 mV at current density of 10 mA cm−2. Meanwhile, we observed an electrochemical corrosion phenomenon associated with the carbon fiber cloth electrocatalyst during the OER tests, especially under high static potentials.
