Synergistic optimization promoted overall water splitting of CoSe@NiSe@MoS heterostructured composites
Herein, the preparation of CoSe@NiSe 2 @MoS 2 composites and the systematic investigation of their water splitting performance as a function of composition have been demonstrated. CoSe@NiSe 2 @MoS 2 -12 with the optimized composition exhibits a current density of 10 mA cm −2 at overpotentials of 81...

Summary: | Herein, the preparation of CoSe@NiSe

@MoS

composites and the systematic investigation of their water splitting performance as a function of composition have been demonstrated. CoSe@NiSe
2
@MoS
2
-12 with the optimized composition exhibits a current density of 10 mA cm
−2
at overpotentials of 81 and 170 mV for HER and OER in alkaline conditions, respectively. The overall water splitting device built using CoSe@NiSe
2
@MoS
2
-12 exhibited a low voltage of 1.48 V at 10 mA cm
−2
due to the synergistic effects.
The CoSe@NiSe
2
@MoS
2
composite exhibits an effective catalytic performance that is comparable to and/or better than many previously reported systems. The efficient electrocatalytic performance is ascribed to the synergetic effect between each component. |
