Hydrothermal synthesis of cobalt sulfide nanotubes: The size control and its application in supercapacitors

Mechanical Alloying Synthesis of Co9S8 Particles as Materials for Supercapacitors

“…Cobalt sulfide nanoparticles were also synthesized through a hydrothermal route and demonstrated a specific capacitance of 478.75 F¨g´1 at a scan rate of 5 mV¨s´1 [13]. Meanwhile, cobalt sulfide nanotubes were prepared by a hydrothermal method and exhibited a specific capacitance of 285 F¨g´1 at a current density of 0.5 A¨g´1 [14]. This research indicates that cobalt sulfides possess excellent pseudocapacitive properties.…”

Polypyrrole/nickel sulfide/bacterial cellulose nanofibrous composite membranes for flexible supercapacitor electrodes

“…Transition metal sulfides (e.g., NiSx, CuSx, CoSx, and VS x ) are attracting increasing interest as electrode materials for supercapacitors and have achieved excellent electrochemical performances because of their relatively high capacitance and excellent redox reversibility (Jun et al 2011;Wan et al 2013;Xia et al 2014;Peng et al 2015;Tang et al 2015). Among the metal sulfides, nickel sulfides have drawn tremendous attention with the advantages of good electronic conduction, high redox activity, low cost, and ease of fabrication (Li et al 2014c).…”

Nickel Sulfide Nanoparticles Synthesized by Microwave-assisted Method as Promising Supercapacitor Electrodes: An Experimental and Computational Study

“…Transition metal sulfides, such as Co 9 S 8 [7], VS 2 [8], CuS [9], and NiCo 2 S 4 [10] have been greatly considered for the electrode materials and have achieved excellent electrochemical performances due to their excellent redox reversibility and relatively high capacity/capacitance [11,12]. Among the metal sulfides, nickel sulfides have drawn much attention with the advantages of good electronic conduction, high redox activity, low cost and ease of fabrication [13].…”
