Fiber-based multifunctional nickel phosphide electrodes for flexible energy conversion and storage

Fiber-based multifunctional nickel phosphide electrodes have been successfully prepared by facile electrodeposition of nickel nanoparticle arrays on a commercial carbon fiber followed by low-temperature phosphidation. With the synergistic effect from the hierarchically porous structure and chemical compositions, the resultant electrodes exhibit excellent performance for overall water-splitting electrocatalysis and flexible supercapacitors.
