Biomolecule-assisted synthesis of cobalt sulfide nanowires for application in supercapacitors

Complex–Surfactant‐Assisted Hydrothermal Synthesis and Properties of Hierarchical Worm‐Like Cobalt Sulfide Microtubes Assembled by Hexagonal Nanoplates

“…[25][26][27] In addition, cobalt sulfides have also been used in solar cells because of their high solar absorption, which is due to the strong intrinsic absorption coupled with surface morphology effects. [28] Due to these important properties, many recent efforts have been dedicated to the synthesis of micro-and nanocrystals of cobalt sulfides with various morphologies, such as Co 9 S 8 and CoS 2 nanoparticles, [29] CoS nanowires, [30,31] thin films, [32] octahedrons of Co 3 S 4 , [25] and sea urchin-like Co 9 S 8 . [33] It is worth noting that Co 3 S 4 nanotubes [34] and cobalt sulfide hollow nanocrystals [35] have been fabricated based on the Kirkendall effect.…”

“…The specific capacitance value is 201 F g À1 , which is quite low compared with a previously reported cobalt sulfide nanowire (508 F g À1 ). [30] This may be due to the more slack structure and larger specific surface area of the cobalt sulfide nanowires.…”

Synthesis of cobalt sulfide nanostructures by a facile solvothermal growth process

“…Diverse cobalt sulfide compounds including CoS, Co 1−x S, CoS 2 , Co 3 S 4 , Co 9 S 8 have been synthesized and their excellent chemical, physical and mechanical properties have been reported [9][10][11][12][13][14][15][16][17]. For instance, CoS have been used to serve as a low-cost replacement for the state-of-the-art EC material RuO 2 in electrochemical capacitors (EC) and as a negative electrode material for rechargeable lithium batteries [18][19][20]. Pyrite CoS 2 is an important half-metallic material and has fundamental physics in spintronics and potential applications in spin-electronic devices due to their open bands containing electrons with a single spin state [21][22][23].…”

Interface-hydrothermal synthesis and electrochemical properties of CoSx nanodots/poly(sodium-4-styrene sulfonate) functionalized multi-walled carbon nanotubes nanocomposite

“…Recently, cobalt sulfide, commonly used as an electroactive material for rechargeable lithium batteries [9], has been investigated as a low-cost ECs electroactive material [10][11][12]. Li et al…”

“…And bimolecular-assisted hydrothermal process was developed by Li and coworkers to synthesize CoS nanowires with a SC of 508 F g À1 in 3 KOH [11]. Particularly, a SC of 910 F g À1 was achieved in 2 M KOH for the CoS x NPs with a size of ca.…”
