Selective Growth of Molybdenum Sulfo-Selenides on a Defect-Rich Carbon Nanotube Skeleton for Efficient Energy Storage and Hydrogen Generation Applications

Abstract

The design of multifunctional advanced nanomaterials is a fascinating and demanding approach to harness clean and sustainable energy. Two-dimensional metallic transition-metal chalcogenide-based alloys are regarded as a viable option for energy storage and hydrogen evolution reaction (HER) applications due to their improved electrical conductivity, presence of additional active sites, and capacity to make hybrids with various materials. Herein, a facile hydrothermal approach is employed to construct 1D/2D MoSSe@f-CNT heterostructures, and their energy storage/conversion performance was investigated. The fabricated asymmetric device based on MoSSe@f-CNT//VSe2/rGO/CNT showed a high specific capacitance of 111 F/g with a high energy density (26 Wh/kg) and power density (11,250 W/kg). Also, the catalyst shows a decent electrocatalytic HER performance with a low overpotential value of 249 mV at a current density (j) of 10 mA cm–2 in a 0.5 M H2SO4 electrolyte.

Elucidating the Energy Storage Performance of 2D Metallic Vanadium Ditelluride/Carbon Nanotube for Next‐Generation Asymmetric Supercapacitors Using Emerging MoSSe/Carbon Nanotube

“…In one of our previous works, we analyzed and established the electrochemical performance of MoSSe/CNT. [ 53 ] We are not repeating the detailed material characterization and electrochemical assessment of MoSSe/CNT but for a quick reference, we have provided the XRD pattern and FESEM images of MoSSe/CNT in Figure S8 and S9, Supporting Information, to establish the purity and morphology of the negative electrode. Also, the basic three‐electrode analysis of the MoSSe/CNT with the long cyclic study is provided in Figure S10, Supporting Information.…”

Recent developments, challenges and future prospects of magnetic field effects in supercapacitors

“…130,131 Studies across the globe revealed that a hybrid formation of these pristine electrode materials can overcome many of these deciencies. [132][133][134] One of the well-established hybrid formations is pseudocapacitor/EDLC hybrids. 128,135,136 In these hybrid electrodes, the overall performance of the supercapacitor benets from the individual advantages of both of these materials through a synergistic interaction.…”
