Hierarchically Porous Nickel Sulfide Multifunctional Superstructures

Multifunctional nickel sulfide superstructures (h-NiSx) with 3D hierarchically porosity are prepared by template-free electrodeposition of porous metallic Ni microspheres arrays on a nickel foam and subsequent low-temperature sulfurization. With the designed nanoscale architecture, the resulting h-NiSx exhibit superior performance and strong robustness for overall water splitting electrocatalysis and capacitance application in alkaline electrolytes.
