Synthesis of hierarchical MoS₂ and its electrochemical performance as an anode material for lithium-ion batteries

Abstract

Hydrothermally synthesized MoS2 products can be tuned from porous flowers to dense spheres by addition of NaOH.

Ultrathin few-layered molybdenum selenide/graphene hybrid with superior electrochemical Li-storage performance

“…The reversible capacity first gradually raised from 624 mAh g À1 to a high level of 859 mAh g À1 and then a continuous capacity decay process appeared. Similar results have been reported in other studies of MoS 2 anodes for LIBs and the reason for this phenomenon is still unknown [45,46]. The reversible capacity gradually decayed with cycle number from 859 mAh g À1 to 500 mAh g À1 after 100 cycles, giving rise to a only 58% capacity retention.…”

Enhanced Efficiency of Dye-Sensitized Solar Counter Electrodes Consisting of Two-Dimensional Nanostructural Molybdenum Disulfide Nanosheets Supported Pt Nanoparticles

“…As we can see from Figure 1a, the PtNPs were uniformly dispersed on the MoS 2 NSs without aggregation. The HRTEM image in Figure 1b shows the plentifully exposed plans with an interlayer distance of the MoS 2 of about 0.64 nm, corresponding to the spacing between (002) planes of MoS 2 , similar to previous studies in Reference [12]. In addition, the HRTEM image clearly shows PtNPs with a uniform size on the MoS 2 NSs, and particle sizes of the PtNPs in the range of 3-5 nm.…”

“…As a typical transition metal dichalcogenide, 2D layered nanostructural molybdenum disulfide (MoS 2 ) is similar to the graphene structure, and is composed of three stacked atomic layers (a Mo layer sandwiched between two S layers, S-Mo-S) [10]. Layered nanostructural 2D MoS 2 has been extensively investigated as a promising catalyst in electrochemical applications in recent years such as H 2 evolution [11], Li-ion batteries [12], and DSSCs [13]. For instance, Jaramillo et al reported electrochemical H 2 production with MoS 2 nanocatalysts based on their catalytically active sites for H 2 evolution [11].…”

Hierarchical MoS2 microspheres prepared through a zinc ion-assisted hydrothermal route as an electrochemical supercapacitor electrode

“…[37][38][39][40] Herein, we present a facile zinc ion-assisted hydrothermal method to prepare hierarchical MoS 2 microspheres assembled by 2D nanosheets, which exhibit superior electrochemical performance as an electrode for pseudcapacitor.…”
