摘要：

Developing high-performance overall water-splitting electrocatalysts working under alkaline condition is highly desirable but many challenges remain. Herein, the in-situ surface-derivation of Ni-Mo bimetal sulfides nanosheets on Co3O4 nanoarrays, which supported on carbon fibers (Ni-Mo-S@Co3O4/CF) was designed and constructed. The as-prepared hybrid catalyst exhibits excellent electrocatalytic performance for both OER and HER under alkaline conditions, with only a small overpotential of 275 mV and 85 mV at a current density of 10 mA cm(-2), respectively. Furthermore, the hybrid catalysts assembled full electrolyzer achieved a current density of 10 mA cm(-2 )at 1.57 V in an alkaline condition, without decay even after a durability test of 50 h. These results demonstrate that in-situ surface-derivation is a promising strategy for the design of efficient overall water splitting catalysts. (C) 2019 Elsevier B.V. All rights reserved.
