Boron monosulfide as an electrocatalyst for the oxygen evolution reaction

Chemical Engineering Journal, vol. 471, pp. 144489

Abstract

The current energy crisis and environmental problems associated with the use of fossil fuels necessitate a transition to clean and sustainable energy carriers like hydrogen produced by electrocatalytic water splitting. Hence, the development of robust, low-cost, and high-performance oxygen evolution reaction (OER) electrocatalysts has attracted considerable attention. Herein, an OER electrocatalyst for use in alkaline media is prepared by hybridising rhombohedral boron monosulfide with graphene to provide electronic conductivity. The catalytic activity of the electrocatalyst (overpotential of 250 mV at 10 mA cm−2) is higher than those of most previously reported counterparts. Our results pave the way for the design of electrocatalysts composed of abundant elements with a wide range of applications in renewable energy devices.
