Abstract
- In this paper, we report the use of Zn 0.76 Co 0.24 S/CoS 2 nanowires array on Ti mesh (Zn-Co-S/TM) topotactically derived from ZnCo 2 O 4 nanowires array precursor as a durable and efficient bifunctional hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalyst in strongly alkaline media. This Zn-Co-S/TM electrode drives 20 mA cm −2 at 238 mV HER overpotential and 20 mA cm −2 at 330 mV OER overpotential. The corresponding two-electrode alkaline water-splitting system achieves 10 mA cm −2 at a cell voltage of 1.66 V. [ABSTRACT FROM AUTHOR]
