“…On the other hand, layered two dimensional (2D) transition metal dichalcogenides (TMDs) such as molybdenum disulphide (MoS 2 ), [37][38][39][40] tungsten disulphide (WS 2 ) and graphene 41 have been used to fabricate electrochemical sensors. 42 As an important candidate, MoS 2 consisting of a S-Mo-S bonded trilayered structure 43,44 (with a band gap in the range of 1.2 to 1.8 eV) has shown high catalytic activity, surface area and electrical conductivity.…”

“…The unique properties of MoS 2 1–3 monolayers thick, including a direct bandgap, have inspired extensive study of electronic, spintronic, and optoelectronic applications . This has also stimulated research into MoS 2 substrates for biosensor applications, as recently reviewed . The methods reported here have two significant advantages over the prior literature, the use of μm thick MoS 2 films that are anchored onto a solid substrate and biomolecule immobilization through strong Mo−S bonds.…”

“…MoS 2 is a promising new substrate material for biosensors that is both electrically conductive and chemically stable, as recently reviewed [24,25]. However, most studies report biomolecular physisorption atop MoS 2 [24,25]. Only a few studies report chemisorption atop MoS 2 , and these studies utilize nanosheets of MoS 2 that are subsequently attached to another substrate material [26][27][28][29].…”

Immobilization of antibody fragments to 3‐phenoxybenzoic acid (3‐PBA), which are created by disulphide bond (S−S) reduction with tris (2‐carboxyethyl) phosphine (TCEP), is reported atop MoS2 and Cu‐doped MoS2 thin films. MoS2 and Cu‐doped MoS2 thin films are electrodeposited using previously reported methods and tested for their ability to immobilize antibody fragments, before and after annealing in Ar at 500 °C for 3 h. This annealing procedure removes excess sulphur in the as‐deposited films, and creates coordinatively unsaturated Mo sites that are highly reactive towards sulphur, as previously reported for MoS2 hydrodesulphurization catalysts. As demonstrated by electrochemical impedance spectroscopy (EIS) measurements, both annealed MoS2 and Cu‐doped MoS2 thin films adsorb antibody fragments through Mo−S bond formation, unlike the as‐deposited films. Impedance detection of 3‐PBA is reported utilizing antibody fragments bound to both materials, with a sensitivity of 2.7×108 Ω cm2 M−1 and a detection limit of 2.5×10−6 M atop MoS2, and a sensitivity of 5.9×108 Ω cm2 M−1 and a detection limit of 3.8×10−6 M atop Cu‐doped MoS2. The rms surface roughness obtained by atomic force microscopy (AFM) measurements atop annealed MoS2 and Cu‐doped MoS2 ranges from 60–140 nm, so the methods described herein are not limited to ultra‐smooth substrates.

“…This unique material, with its special layered structure, has attracted significant interest in energy-based research. [27][28][29][30] It has many advantages: (1) extraordinary crystal, physical, chemical, electronic and photosensitive properties; [18,[31][32][33][34][35][36][37][38] (2) bandgap-adjustable properties (direct band-gap of ∼1.8 eV), potentially to be applied in electronic devices, which promotes applications containing energy conversion and storage, catalysts, and electronic devices; [31,[39][40][41][42] (3) the 2D nanostructure of MoS 2 offers a large number of active sites. These sites originate from the under-coordinated sulphur atoms at the edges, thus leading to platinum-like catalysis activity.…”

Energy storage devices with high performance have been extensively studied for decades due to the increasing fuel demands. The physicochemical properties of 2D materials such as MoS 2 and graphene, due to their high surface area, versatile electronic structure, high mechanical robustness, This article is protected by copyright. All rights reserved. 2 high electrical conductivity, and desirable electrochemical characteristics, make them superior candidates for energy storage applications. MoS 2 /graphene composites specially emerge as exceptional candidates that could offer new solution for energy storage applications. Many fabrication strategies to develop and synthesize MoS 2 /graphene composites have been explored and introduced, such as hydrothermal and solvothermal treatment, chemical vapor deposition, sonication, microwave and self-assembly. For these composites to be suitable for energy storage devices applications, they are often integrated with other materials such as additional agents to improve their electrochemical and stability properties. In this review, recent progresses on the development of graphene/MoS 2 composites for energy storage and conversion applications (supercapacitors, batteries, solar cells, and hydrogen evolution) is presented and discussed. Critical review and perspectives on the future directions for MoS 2 /graphene composite based energy storage devices are also presented as concluding remarks. Recent progress on the development of graphene/MoS 2 composites for energy storage applications is also presented and discussed.
