Abstract:

A new NO2 nanohybrid of a gas sensor (CTAB-MoS2/rGO) was constructed for sensitive room-temperature detection of NO2 by 3D molybdenum disulfide (MoS2) and reduced graphene oxide (rGO), assisted with hexadecyl trimethyl ammonium bromide (CTAB). In comparison with MoS2 and MoS2/rGO, the BET and SEM characterization results depicted the three-dimensional structure of the CTAB-MoS2/rGO nanohybrid, which possessed a larger specific surface area to provide more active reaction sites to boost its gas-sensing performance. Observations of the gas-sensing properties indicated that the CTAB-MoS2/rGO sens

In this paper, we report a facile strategy to design and prepare reduced graphene oxide (rGO) supported MoS2 nanoplatelet (MoS2/rGO) via a solvothermal co-assembly process. It is found that in the as-obtained MoS2/rGO nanocomposite, MoS2 possesses unique platelet structure and rGO is exfoliated due to the in situ growth of MoS2 nanoplatelet, leading to a large specific surface area, facilitating rapid diffusion of lithium ions. The nanocomposite is used as a promising anode material for lithium-ion batteries and displays a high initial charge capacity (1382[Formula: see text]mA[Formula: see te

Abstract:

This study presents three-dimensional (3D) MoS2/reduced graphene oxide (rGO)/graphene quantum dots (GQDs) hybrids with improved gas sensing performance for NO2 sensors. GQDs were introduced to prevent the agglomeration of nanosheets during mixing of rGO and MoS2. The resultant MoS2/rGO/GQDs hybrids exhibit a well-defined 3D nanostructure, with a firm connection among components. The prepared MoS2/rGO/GQDs-based sensor exhibits a response of 23.2% toward 50 ppm NO2 at room temperature. Furthermore, when exposed to NO2 gas with a concentration as low as 5 ppm, the prepared sensor retains a respo

Abstract:

In this work, a novel electrochemical aptasensor for the detection of ochratoxin A (OTA) was developed using a three-dimensionally ordered macroporous (3DOM) reduced graphene oxide–Au nanoparticles–molybdenum disulfide (RGO-AuNPs-MoS2) composite material as the sensing interface and Au nanoparticles–carbon-coated ferroferric oxide (AuNPs-Fe3O4@C) composite as the signal amplifier. The 3DOM RGO-AuNPs-MoS2 composite exhibited excellent conductivity and catalytic activity. The 3DOM RGO-AuNPs-MoS2 film was electrodeposited onto the Au electrode surface to immobilize DNA capture probe (CP), which w

Layered 2D transition metal dichalcogenides (TMD’s) have been considered as an important class of materials in the field of energy and environmental applications. Therefore, it is desirable to fabricate 2D hybrid TMD’s materials in simple solution processing methods. In this study, MoS2-RGO hybrid 2D few layered sheets are produced by supercritical fluid process (SCF) by using ethanol as solvent at 250 ºC in a short duration of 0.5 h.

Abstract:

Due to their unique tubular and spiral structure, graphene and graphene oxide nanoscrolls (GONS) have shown extensive applications in various fields. However, it is still a challenge to improve the optoelectronic application of graphene and GONS because of the zero bandgap of graphene. Herein, ammonium tetrathiomolybdate ((NH4)2MoS4) was firstly wrapped into the ((NH4)2MoS4@GONS) by molecular combing the mixture of (NH4)2MoS4 and GO solution on hydrophobic substrate. After thermal annealing, the (NH4)2MoS4 and GO were converted to MoS2 nanosheets and reduced GO (RGO) simultaneously, and, thus,

Abstract:

Since the successful preparation of single-layer graphene in 2004, two-dimensional materials have gradually become one of the research hotspots in the field of materials science. However, due to the inevitable defects of intrinsic two-dimensional materials, researchers began to explore how to obtain more excellent two-dimensional materials. In this paper, the basic properties, preparation methods and application in gas sensors of MoS2/rGO composites are reviewed. This paper has a certain reference value for the research of two-dimensional materials used in gas sensors.
