CoNi2S4 nanoparticle on carbon cloth with high mass loading as multifunctional electrode for hybrid supercapacitor and overall water splitting

Transition-metal sulfides are regarded as one of the most potential materials for the supercapacitor and electrocatalyst, and the holey alignments of the active materials with effective availability is highly required due to the rich active sites and convenient electrolyte access for surface reaction. Herein, we report the growth of CoNi2S4 nanoparticles with high mass loading (14.8 mg cm−2) on the surface of carbon cloth (CC) by a two-step...
