“…They obtained the following results for the specified times: 10.74, 13. and 13.26 m 2 g −1 and pore diameters of 0.047421, 0.042381, 0.064782 and 0.03525 respectively. These results showed that the maximum surface area and pore volu exhibited at 36 h reaction time [27].…”

“…The specific surface area is also impacted by the reaction time as Manuraj et al showed in their work [27]. They synthesised MoS 2 nanostructures using different reaction times (i.e., 12, 24, 36, 48 h) and proceeded, with BET analyses, the measurements of the surface area.…”

“…Tang et al [27] synthesised MoS 2 by the hydrothermal method, obtaining irregular nanosheets aggregated together to form flower-like structures of approximately 1-2 µm in size using about 180 mg of CTAB. They conducted a EDX analysis that revealed that the nanoflowers consisted of Mo and S elements.…”

“…Besides this, many research groups [26][27][28][29][30] found that another promising material for supercapacitor construction is molybdenum disulfide (MoS 2 ). Because MoS 2 is easily intercalated by other compounds and has a great theoretical capacitance (±1000 F•g −1 ), it can be used to build layered electrode materials for the construction of supercapacitors [31].…”

Advances in energy storage and energy conversion play an essential role nowadays because the energy demands are becoming greater than ever. To overcome the actual performances of the materials used to build supercapacitors, a combination of transition metal dichalcogenides (TMDCs) and graphene oxide (GO) or reduced graphene oxide (rGO) as graphene-based structures are often studied for their excellent properties, such as high specific area and good electrical conductivity. Nevertheless, synthesis pathways and parameters play key roles in obtaining better materials as components for supercapacitors with higher technical performances. Driven by the desire to understand the influence of the structural and morphological particularities on the performances of supercapacitors based on MoS2/graphene oxide (GO) composites, a survey of the literature was performed by pointing out the alterations induced by different synthesis pathways and key parameters to the above-mentioned particularities.

“…[99] R ct can be evaluated from the length of the diameter of the depressed semicircular arc which arises mainly due to the charge transfer resistance between the electrode and the electrolyte. [100] The Nyquist plots (within 10 À 2 Hz-10 5 Hz frequency range and at a 0.2 V potential) for the α-Fe 2 O 3 electrode material at different electrolyte concentrations are shown in Figure 6. In the Nyquist plot, a semicircular arc in the high-frequency region is absent whereas the Warburg line in the low frequency region is visible.…”

The nano-sized bush-like α-Fe 2 O 3 particles were synthesized using sol-gel auto combustion route. The structural characterization of obtained α-Fe 2 O 3 was performed by X-ray diffraction (XRD) method to confirm its phase and crystallinity. The Scanning Electron Microscopy (SEM) confirmed the formation of bush-like nanostructure which was further used for the electrochemical charge storage performance testing. The electrochemical performances of the synthesized electrode material were studied by using Cyclic Voltammetry (CV) and electrochemical impedance spectroscopy (EIS) analysis in a three electrode configuration. The variation of specific capacitance values with the different molar concentration of electrolyte has been discussed. An enhancement in the specific capacitance has been observed up to 3 M KOH electrolyte solution. The maximum value of specific capacitance is 202.2 F g À 1 which is obtained at a scan rate of 2 mV s À 1 for 3 M aqueous KOH solution as electrolyte.
