Time-dependent exfoliation study of MoS₂ for its use as a cathode material in high-performance hybrid supercapacitors

Abstract

Quick and precise exfoliation of bulk molybdenum sulphide into few layers can bring a quantum jump in the electrochemical performance of this material. Such a cost-effective exfoliation route, to obtain...

Molybdenum disulfide, exfoliation methods and applications to photocatalysis: a review

“…Cathodic exfoliation is typically performed in organic solvents such as dimethyl sulfoxide (DMSO). 18–64 El Garah et al presented a rapid (<1 hour) electrochemical exfoliation method for molybdenum disulfide (MoS 2 ) using lithium-ion intercalation, with a lithium chloride solution in DMSO as the electrolyte. Their results pave the way for a rapid and ambient condition preparation of MoS 2 nanoflakes with an average lateral size of about 0.8 μm, suitable for low-cost electronic (optoelectronic) devices.…”

“…This variety of forms can be controlled by choosing appropriate synthesis routes with optimized operational parameters. 17–33…”

“…This variety of forms can be controlled by choosing appropriate synthesis routes with optimized operational parameters. [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] In fact, when changing the measurement scale, the properties or behavior of materials also change. Thus, individual layers of MoS 2 have radically different properties compared to bulk materials.…”

Green synthesis of heterolayered 2D nanohybrid catalytic hydrogel cell for environmentally-friendly water splitting

“…13 However, organic solvents (such as N -methyl-2-pyrrolidone and dimethylformamide, dimethyl sulfoxide, and acetonitrile) are widely employed due to their appropriate surface tension (40 mJ m −2 ) when exfoliating the 2D materials, resulting in a negative impact on the environment and health issues. 14–16 Even though hydrothermal/solvothermal reactions and chemical vapor deposition processes have been in use as alternative methods for overcoming the issue of toxic solvents, however, these processes are accompanied by harsh process conditions (such as higher pressures and temperatures). 17 Although multiple studies have examined the exfoliation of 2D materials, such as MoS 2 , using amphiphilic macromolecules, the transformation of these materials into a different phase remains a difficult task.…”
