Abstract

Energy conversion and storage systems such as water splitting metal-air batteries require high-performance and durable oxygen evolution reaction (OER) catalysts. Herein, we report the in situ development of self-standing Co3O4 nanorods array on Co foil (Co3O4 NA/CF) as a 1D OER catalyst electrode. Such Co3O4 NA/CF only needs overpotential of 308 mV to drive a geometrical catalytic current density of 15 mA cm-2 in 1.0 M KOH with good long-term electrochemical durability. In addition, this catalyst achieves a high turnover frequency of 0.646 mol O2 s-1 at overpotential of 410 mV.
