A route to synthesis molybdenum disulfide-reduced graphene oxide (MoS2-RGO) composites using supercritical methanol and their enhanced electrochemical performance for Li-ion batteries

In situ production of a two-dimensional molybdenum disulfide/graphene hybrid nanosheet anode for lithium-ion batteries

“…Most importantly, the 2D MoS 2 /graphene hybrid nanosheets structure is capable of tolerating volume variation of the electrodes during Li-ions extraction/insertion, enhancing Li-ions storage kinetics and structural stability. The obtained electrochemical performance of the 2D MoS 2 /graphene hybrid electrode is promising and comparable with those of the reported results [21][22][23][24][25][26][27][28][29] as summarised in Table S1 (ESI). † It is expected that a more robust electrode architecture of MoS 2 /graphene hybrid nanosheets prepared by controlled parameters could be used as an effective negative electrode for more sustainable, costeffective Na-ion and K-ion batteries and this is to be demonstrated in our future work.…”

MoS2/Graphene Composites as Promising Materials for Energy Storage and Conversion Applications

“…[129] Solution method is also popular, including all solution method, [130] and solution chemistry method, [131,132] because of the excellent solution conditions. Moreover, other methods, such as reflux method, [25] one-pot synthesis, [57,133,134] freeze-drying, [135] drop-casting, [136] etc., are considered for constructing the MoS 2 /graphene composite for energy storage application. system, thus obtaining unique properties and novel functionalities for many clean energy-related application, which is an extremely efficient response to the gradual depletion of traditional energy and the increasing environmental pollution.…”

Application of MoS2 in the cathode of lithium sulfur batteries

“…Namjo et al 68 obtained a uniform MoS 2 coating on the surface of porous carbon structures with nano-sized pores by chemical vapor deposition. Mugyeom et al 69 synthesized MoS 2 -SRGO composites by onepot deposition of MoO 2 on SRGO and simultaneous reduction of GO to SRGO in supercritical methanol followed by sulfurization. The obtained MoS 2 -SRGO composites contain an 11-14 layer crystalline MoS 2 phase.…”
