Catalyst-free grown carbonaceous MoS2 nanoworm electrodes for symmetrical supercapacitors

Enhanced hydrogen evolution and symmetric supercapacitor performance of a Ru-doped multiphase WS2 electrode

“…It is noted that the 2H/1T-WS 2 -10 electrode has higher specific capacitance (664 F g −1 ) and energy density (92 W h kg −1 ) than 2H-WS 2 (269 F g −1 and 37 W h kg −1 ), 2H-WS 2 -2 (460 F g −1 and 64 W h kg −1 ) and 2H-WS 2 -6 (462 F g −1 and 66 W h kg −1 ) electrodes. The supercapacitor performance of the 2H@1T multiphase Ru doped WS 2 electrode is close to the literature report of 2D TMD based symmetric or asymmetric supercapacitor cells 36–52 (Table 1).…”

“…4a) and and 66 W h kg −1 ) electrodes. The supercapacitor performance of the 2H@1T multiphase Ru doped WS 2 electrode is close to the literature report of 2D TMD based symmetric or asymmetric supercapacitor cells [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] (Table 1).…”

Mn Incorporated CeO2 Lattice Endorsement of Electrochemical Performance in Symmetric Supercapacitor Device

“…The SC has various advantages over batteries, as it offers higher power densities, faster charging time, and longer cycling life. [1][2][3][4][5][6][7][8][9][10] As with batteries, SC devices are also composed of four main parts: positive and negative electrodes, a separator, and a suitable electrolyte. SC performance and cost are largely determined by electrode materials out of these four components.…”

Comparison of Kinetics of Adsorption of Permanganate on Co-Al-Layered Double Hydroxide and MoS2 Nanocompounds

“…MoS 2 shows polytypism and has three various configurations like 1T, 22 2H 23 and 3R 24 that represent its trigonal, hexagonal and rhombohedral arrangements, respectively and among them 2H is the most stable thermodynamic form of MoS 2 . 23 MoS 2 possesses many applications such as solid lubricant, 25 biosensor, 26 gas sensor, 27 catalyst, 28 supercapacitor 29 and for tissue engineering, 30 electronic and optoelectronic devices, 31 energy storage, 32 solar energy storage, 33 and biomedical applications. 34 Potassium permanganate (KMnO 4 ), known as "Condy's Crystal", is a strong oxidizing inorganic compound and has many applications like medical uses, 35 water treatment process 36 , analytical uses 37 and synthesis of organic compounds 38 in laboratories and industry.…”
