Hydrothermal synthesis of molybdenum disulfide nanosheets as supercapacitors electrode material

Facile one-step hydrothermal preparation of molybdenum disulfide/carbon composite for use in supercapacitor

“…The CV curves are close to rectangular shape, demonstrating that all samples exhibit typical electric double-layer capacitive character. The formation of electric double-layer capacitance in MoS 2 is in good accordance with the previous literatures [27,38,51]. Obviously, the MoS 2 /C composite has a higher C s than pure MoS 2 and carbon at the same scan rate, because of its larger enclosed area in the CV curve.…”

“…The C s of MoS 2 /C composite is over ten times higher than that of MoS 2 and nearly three times that of carbon. This value is evidently higher than those of other MoS 2 [27,36,51] and is comparable to that of the only MoS 2 /C composite prepared by an expatiatory method [37]. Besides, the equivalent series resistance (ESR) of supercapacitors based on MoS 2 , C and MoS 2 /C composite can be obtained according to Eq.…”

Synthesis of molybdenum disulfide/carbon aerogel composites for supercapacitors electrode material application

“…1A) has a surface morphology with many corrugations and scrolling. As can be seen from Our previous work has demonstrated that the MoS 2 nanosheet exhibits reversible type II isotherms and its specific surface area is 21.1 m 2 g -1 [38]. It is known that specific capacitance of electrical double-layer capacitor strongly depends on surface area.…”

Electrochemical Applications of Two-Dimensional Nanosheets: The Effect of Nanosheet Length and Thickness

“…While the 1T-polytype 33 of MoS2 has demonstrated high capacitance, electrodes made from the 2H-polytype of a number of TMDs have shown lower performances. [66][67][68][69][70] Because the aim of this work is not to demonstrate high-performance supercapacitors but to explore the effect of nanosheet dimensions on the performance of supercapacitor electrodes, we have opted to use size-selected 2H-WS2 nanosheets as a model system. An EDLC stores energy by localising non-Faradic charges at an electrode-electrolyte interface.…”
