Enhanced Performance of Nanostructured WSe2 as an Electrode Material for Supercapacitor

Since last few years, there has been a considerable rise in research focused on the engineering applications of 1D and 2D inorganic oxide-layered materials, with particular emphasis on transition metal dichalcogenides. However, despite WSe2 being an important layered material with potential uses in energy storage and other areas, its investigation has been restricted due to issues concerning its synthesis and other related factors. Recently, researchers have discovered that the 2D form of WSe2 can be successfully used in photodetectors, field effect transistors, and other novel optoelectronic devices. Our study aims to explore the potential of WSe2 further by developing a cost-effective hydrothermal method for synthesizing WSe2 nanostructures with enhanced performance. By employing a range of characterization techniques, including UV–vis spectroscopy, PL spectroscopy, FESEM, Raman spectroscopy, and X-ray diffraction, we were able to gain insights into the properties and structure of the synthesized material. Furthermore, we assessed the material's applicability as an electrode material for supercapacitors by performing cyclic voltammetry to calculate its capacitance. Our work contributes to the expanding field of materials science and engineering, with a focus on energy storage, by providing new perspectives on the synthesis, characterization, and potential applications of WSe2 nanostructures.
