“…In another work, Mandal et al prepared 1T-VS 2 electrodes to fabricate an in-plane micro-supercapacitor via a simple mask-assisted printing method. [79] According to the results, as-fabricated micro-supercapacitor demonstrated a specific capacitance of 212.7 mF cm À 2 at a scan rate of 10 mV s À 1 and a retention rate of 97.6 % after 1000 cycles. The advantage of this study is that a micro-capacitor could be easily produced using low-cost and simple production techniques.…”

Supercapacitor (SC) devices holds an important position between traditional capacitors and ion batteries in terms of energy density and power density values. In particular, SC′s greater power density values than Li‐ion batteries make them useful for some specific applications, such as storing energy in hybrid cars while the car slows down. Increasing energy density values is one of the key challenges for the SC community. Transition metal dichalcogenides (TMDCs), are one of the new developing important material systems to have this potential, compared to their counterparts’ transition metal oxides and conductive polymers. This review is about giving insight into the electrochemical performances of two‐dimensional (2D) layered transition metal sulfides (TMS) such as MoS2, WS2, TaS2, NbS2, VS2, TiS2 and ZrS2 materials. On the other hand, the methods mostly used in synthesizing these materials are presented.

“…It has many exceptional properties, likehigh electrical conductivities, 2D layered structure, large surface area, and high active sites which make it a promising material for energy storage application [7]. Like other TMS material, vanadium disulfide (VS2) is formed of layered structure, in which the vanadium (V) atom is sandwiched in between two sulfur (S) atoms [8][9][10][11]. There exists a weak van-der-Waals force in-between these layers, which facilitates the transport of ions and electrons.…”

Vanadium disulfide (VS2), which belongs to transition metal dichalcogenides (TMDs) group, is a prominent material for energy storage application. On the other hand, graphene like carbon-based nanomaterials offer improved electrochemical performance due to high specific surface area, excellent conductivity, good chemical, and mechanical stability. Therefore, composite of graphene like material with TMD have shown better electrochemical performance till date. In this work, we have synthesized VS2/N-rGO composite material, which can be applicable for energy storage device. At first, we have synthesized graphene oxide (GO) using Tour method. Then we reduced GO along with nitrogen doping using hydrothermal route. After that, we have synthesized VS2/N-rGO by hydrothermal method. The X-ray diffraction (XRD) spectrum of GO shows a prominent peak at 10.2°, which implies the interlayer spacing in GO of 8.7 Å. After reduction and doping with nitrogen (N), two peaks are obtained at 24.7° (d = 3.6 Å), and 42.3° (d = 2.1 Å) in the XRD pattern which corresponds to N-rGO. RAMAN spectrum of composite shows the characteristics peaks of VS2 at 141.6, 194.5, 286.4, 404.1, 680.1 and 997.2 cm-1 along with D and G bands coming from the N-rGO. We have also performed the Fourier-transform infrared-spectroscopy (FTIR) and Field-emission gun-scanning electron-microscopy (FEG-SEM) characterizations to investigate the bonding vibration and surface morphology of the materials. The synthesized material is suitable for energy storage applications.

“…However, hydrothermal route is a simple route to synthesize WO3 nanostructure at a low cost. Previously, we have reported the hydrothermal synthesis of 2D TMD (transition metal dichalcogenides) material [6][7][8][9]. In this process, a large amount of nanomaterial can be obtained at high pressure and low temperature.…”

Tungsten oxide (WO3), which is also known as tungsten trioxide and wide band gap semiconductor material has drawn enormous attention among researchers due to its fascinating properties. Using facile one step hydrothermal method, the synthesis and characterizations of highly crystalline 1D nanorod of WO3 are presented in this paper with large scale production of the material. Several characterization techniques, such as transmission electron microscopy (TEM), field emission gun-scanning electron microscopy (FEG-SEM), X-ray diffraction (XRD), UV-vis spectroscopy have been employed to check the crystallinity, surface morphology, shape, and band gap of the nanomaterial. The XRD data confirms about the highly crystalline hexagonal phase of WO3, which agrees well with the JCPDS card no – 01-085- 2459. Nanorod like morphology can be seen in the low-resolution TEM image. In the HRTEM image, the highly crystalline nature of the material is clearly visible and the obtained interplanar spacing is 0.38 nm which matches with the interplanar spacing of (002) plane. The FEG-SEM image shows the 1D nanorod morphology of the synthesized material. The diameters of the nanorods are in the range of 50-300 nm. The Fourier transform infrared spectroscopy (FTIR) revels the structural information about the synthesized material. The broad peak around 805 cm-1 is attributed to the W-O-W bond stretching vibration. Two other peaks appeared at 1405 and 1628 cm-1 are representing the vibration mode of W-OH bond. We have also studied the UV-vis absorption spectroscopy of the WO3 nanorod to investigate the light absorption property of the material. The band gap obtained from the Tauc plot is 3.16 eV, indicates the wide and direct band gap formation of WO3 nanorod. The synthesized material is suitable for various applications, such as gas sensing, UV photodetector, supercapacitor, and photocatalyst.
