Here we present the study of supercapacitors based on molybdenum disulfide and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (MoS 2 /PEDOT: PSS) composite electrodes deposited by spray-coating. To produce the MoS 2 / PEDOT:PSS composite ink, dispersions of hydrothermally synthesized MoS 2 and PEDOT:PSS were mixed in different weight proportions. Electrodes containing only PEDOT:PSS and MoS 2 were also fabricated for comparison. The composite films were deposited by transferring the as-prepared inks to an airbrush coupled to a modified 3D printer base with in-line displacement. The films were characterized in terms of the scanning electron microscope (SEM), Raman spectroscopy, and sheet resistance. The electrochemical properties of supercapacitors were evaluated by cyclic voltammetry (CV), galvanostatic charge/discharges (GCD) techniques, impedance spectroscopy (IS), and their correlated parameters. The maximum specific capacitance of the MoS 2 -basedsupercapacitor was estimated to be 145.9 F g −1 at 1 mV s −1 , while the 3:1 MoS 2 /PEDOT:PSS weight ratio supercapacitor exhibited a specific capacitance of 131.1 F g −1 . Despite the slightly lower C SP , the 3:1 device provided a better overall performance, with a remarkably higher energy density of 11.2 Wh kg −1 and a maximum power density of 1020 W kg −1 . It also displayed better longterm cycle stability, retaining 92% of its initial capacitance after 1000 CV cycles (against 54% of MoS 2 devices). In summary, we demonstrated the study and production of a high-performance supercapacitor with spray-deposited MoS 2 / PEDOT:PSS composite electrodes, in which the production can be easily scalable for mass production and practical applications.

“…There are two types of sensors that MoS 2 nanostructures have found applications in: chemical/biosensors and gas sensors. Low noise level, high career mobility, and a great surface‐area‐to‐volume ratio of MoS 2 have made it a great candidate for biosensors 127–131 . Moreover, the high available surface of MoS 2 can easily absorb gas molecules and allows the electrons to infiltrate and transport freely in its structure, so that various chemical vapors such as NH 3 , H 2 , and NO could be filtered by MoS 2 nanostructured materials 132–136 …”

Being confronted with the energy crisis and environmental problems, the exploration of clean and renewable energy materials as well as their devices are urgently demanded. Dye‐sensitized solar cells (DSSCs) have attracted widespread attention in recent years as potential cost‐effective alternatives to silicon‐based and thin film solar cells. Two‐dimensional (2D) graphene‐like transition metal dichalcogenides (TMDs), such as WS2 and MoS2, have showed vast potential as novel energy materials due to their unique physicochemical properties. In this review, we outline the applications of WS2 and MoS2 as counter electrode materials in DSSCs. First, a brief introduction of structures and basic properties of WS2 and MoS2 are presented. Then, we summarize the exciting progress of these two materials for DSSCs. Finally, the prospect and further developments in these exciting fields of TMDs are also suggested.

“…Similarly, MoS 2 -based nanocomposites have been used for enzyme-free glucose detection. MoS 2 flowers with a large surface area were synthesized by a hydrothermal method using cetyltrimethylammonium bromide (CTAB) as a surfactant [25]. The morphology of the microflowers can be controlled by the pH of the reaction solution, concentration of CTAB surfactant, and annealing temperature.…”

High-performance glucose biosensors are highly desired for healthcare. To meet these demands, glucose biosensors, particularly enzyme-free glucose biosensors, have received much attention. Two-dimensional materials, e.g., graphene, with high surface area, excellent electrical properties, and good biocompatibility, have been the main focus of biosensor research in the last decade. This review presents the recent progress made in enzyme-free glucose biosensors based on MoS 2 nanocomposites. Two different techniques for glucose detections are introduced, with an emphasis on electrochemical glucose biosensors. Challenges and future perspectives of MoS 2 nanocomposite glucose biosensors are also discussed.
