3D hierarchical ZnCoS@Ni(OH) nanowire arrays with excellent flexible energy storage and electrocatalytic performance.

It is essential for energy storage and conversion systems to construct electrodes and electrocatalysts with superior performance. In this work, ZnCoS@Ni(OH) nanowire arrays are synthesized on nickel foam by hydrothermal methods. As a supercapacitor electrode, the ZnCoS@Ni(OH) structure exhibits a specific capacitance of 1,263.
