“…For example, Su et al decorated AuNPs on the surface of MoS2 nanosheet to obtain high-performance nanocomposites. Such nanocomposites modified electrodes have been proved as excellent sensing ability for dopamine, uric acid and glucose detection [1417][1418][1419] . The further study suggested that MoS2-based nanocomposites could efficiently load hemoglobin to construct an electrochemical sensing platform for hydrogen peroxide (H2O2) detection due to their good biocompatibility 1420 .…”

Research on two-dimensional (2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications.In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief background 物理化学学报 Acta Phys. -Chim. Sin. 2021, 37 (12), 2108017 (3 of 151) introduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials (PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.

“…This is normally altered by functionalizing them with noble metal NPs and carbon-based nanostructures. [33] Herein, we communicate the benefits of the as-prepared pristine 3D MoS 2microflower-modified electrodes by studying the electron transfer mechanisms and the electrochemical properties. The electron transfer mechanisms of the bare (GC and CP) and modified electrodes (MoS 2 /GCE and MoS 2 /CPE) were examined by utilizing the Electrochemical Impedance Spectroscopy (EIS) measurements in 1 mM K 4 [Fe (CN) 6 ] containing 0.1 M KCl.…”

We report the fabrication and analytical performance studies of electrochemical sensors based on hydrothermally grown 3D MoS 2 -microflower-modified Glassy Carbon (GCE) and Carbon Paste Electrodes (CPE) for the sensitive detection of the insecticide imidacloprid (IMI). As compared to MoS 2 /GCE, the fabricated MoS 2 /CPE demonstrates a faster electron transfer and better catalytic ability. MoS 2 /CPE sensor delivers its best performance towards the determination of IMI in PBS solution of pH 7.4, owing to its porous nature which can accommodate a higher number of active electrochemical reaction sites. The sensor exhibits a sensitivity value of 2.296 μA μM À 1 cm À 2 with lower detection and quantification limits of 12 � 0.24 nM and 40 � 0.8 nM respectively. The proposed sensor also exhibits linearity in the detection of IMI from 1 to 100 μM.

“…MoS 2 is the preferred and most applied TMDC for these sensors, but wide applications in this field have been also demonstrated for MoSe 2 . Except in a few cases [ 49 , 61 , 75 , 93 ], Mo-based sensors rely on composite materials where the Mo-dichalcogenides are activated mainly with noble metals [ 60 , 83 , 84 , 91 , 97 , 102 , 114 , 115 , 116 ] and carbon nanostructures [ 77 , 78 , 84 , 96 , 97 ], like graphene or graphene oxide. In particular, AuNPs was the most considered noble metal additive, because of the high affinity of gold for the sulfur atom and the other chalcogenide elements, which allows the controlled synthesis of AuNPs on TMDC nanosheets.…”

Mo-based layered nanostructures are two-dimensional (2D) nanomaterials with outstanding characteristics and very promising electrochemical properties. These materials comprise nanosheets of molybdenum (Mo) oxides (MoO2 and MoO3), dichalcogenides (MoS2, MoSe2, MoTe2), and carbides (MoC2), which find application in electrochemical devices for energy storage and generation. In this feature paper, we present the most relevant characteristics of such Mo-based layered compounds and their use as electrode materials in electrochemical sensors. In particular, the aspects related to synthesis methods, structural and electronic characteristics, and the relevant electrochemical properties, together with applications in the specific field of electrochemical biomolecule sensing, are reviewed. The main features, along with the current status, trends, and potentialities for biomedical sensing applications, are described, highlighting the peculiar properties of Mo-based 2D-nanomaterials in this field.
