Humate-assisted Synthesis of MoS2/C Nanocomposites via Co-Precipitation/Calcination Route for High Performance Lithium Ion Batteries

“…In Fig. 1 a, the broad peaks centered at 3400 cm − 1 were ascribed to the stretching vibrations of −OH, −COOH, and H 2 O bonds, The peaks at 1627, 1413, and 1050 cm − 1 were attributed to the stretching vibrations of the −COO groups and −CH, −OH and so on [ 41 ], respectively, indicating the rich oxygen-containing functional groups on the surface of pure potassium humate, which is beneficial to complexation reaction or adsorption. TGA curve of the homogeneous mixture of Mo-HA precursor and anhydrous Na 2 SO 4 (with a proportion of 1:10) in an argon atmosphere with a heating rate of 10 °C min − 1 is shown in Fig.…”

Interface Synergistic Effect from Layered Metal Sulfides of MoS2/SnS2 van der Waals Heterojunction with Enhanced Li-Ion Storage Performance

“…9−13 Kim et al created MoS 2 /reduced graphene oxide (MoS 2 /rGO) composites, in which fewer layers MoS 2 were uniformly distributed and anchored on the surface of rGO, displayed a higher specific capacity of 1102 mAh g −1 at 0.05 A g −1 after 140 cycles and remarkably enhanced rate capability of 469 mAh g −1 at 2.5 A g −1 than pristine MoS 2 as anode for LIBs. 14 All of these confirmed that graphene could improve electrical conductivity and buffer volumetric change of the compound materials. Moreover, atomic-doped graphene (e.g., N and S) and 3D graphene possess higher conductivity and are applied in composite materials to enhance LIBs' electrochemical activity.…”

“…Author: However, reports have clearly stated that pure SnS 2 (or MoS 2 ) possesses inherent low electrical conductivity and also is accompanied by irreversible volume expansion during the cycling, which eventually results in poor performance. , Highly conductive and flexible graphene is a superior choice to ameliorate LIBs’ capability. Several groups’ research discovered that diverse nanostructures complexes of LMS and graphene prepared through different methods (e.g., microwave, solvothermal, and chemical vapor deposition) exhibited better rate performance, longer cycle life, and better cycle stability than pristine LMS. − Kim et al created MoS 2 /reduced graphene oxide (MoS 2 /rGO) composites, in which fewer layers MoS 2 were uniformly distributed and anchored on the surface of rGO, displayed a higher specific capacity of 1102 mAh g –1 at 0.05 A g –1 after 140 cycles and remarkably enhanced rate capability of 469 mAh g –1 at 2.5 A g –1 than pristine MoS 2 as anode for LIBs .

A molybdenum disulfide-reduced graphene oxide nanocomposite as an electrochemical sensing platform for detecting cyproterone acetate

“…On the other hand, the oxidation temperatures of the MoS 2 in the nanocomposite were higher than that of pristine MoS 2 , indicating that the oxidative stability of MoS 2 in the nanocomposite was enhanced. 34 Meanwhile, the oxidative decomposition temperatures of the rGO in the nanocomposite were decreased, suggesting that MoS 2 particles were closely and tightly anchored to rGO. 34…”
