1T and 2H mixed phase WS₂ nanoflakes decorated with quasicrystal nanosheets for NO₂ sensors

Abstract

Real-world sensing applications require the development of new nanomaterials for the detection of existing molecules. Herein, we fully explore the properties of two-dimensional-Quasicrystal (QC) nanosheets and WS2 nanoflakes to NO2...

Quasicrystal Nanosheet/α-Fe2O3 Heterostructure-Based Low Power NO2 Sensors: Experimental and DFT Studies

“…The multicomponent (Al 70 Co 10 Fe 5 Ni 10 Cu 5 ) high entropy alloy two-dimensional quasicrystal (2D QC) nanosheets were prepared using a liquid phase exfoliation method initiated through the application of high-amplitude sonication waves, which generated significant shear forces on the surface of the bulk material QC and break in 2D sheets. The detailed process of quasicrystal preparation is given in our previous report …”

“…The detailed process of quasicrystal preparation is given in our previous report. 40 Characterization. The synthesized sample's microstructures were analyzed using Carl Zeiss GeminiSEM 500 NanoVP scanning electron microscopy (SEM).…”

“…In addition to their unique structures, QCs exhibit intriguing characteristics, such as high hardness, high surface energy, remarkable resistance to oxidation, the ability for hydrogen storage, and outstanding catalytic performance. , Thanks to these characteristics, QCs have the potential to be used in a wide variety of applications. Multiple aspects of quality control materials have been the subject of extensive research endeavors. , Moreover, they have anisotropic mechanical characteristics that can be used to exfoliate them into a single or few layers. − …”

Strategic review of gas sensing enhancement ways of 2D tungsten disulfide/selenide-based chemiresistive sensors: decoration and composite

“…19–27 In the past few years, the family of 2D materials has witnessed significant expansion, encompassing TMDCs that include MoS 2 , WS 2 , NbSe 2 , MoSe 2 , MoTe 2 , WSe 2 , SnS 2 , SnSe 2 , In 2 Se 3 and violet phosphorus (VP) as well as black phosphorus, MXenes, and layered metal oxides (like MoO 3 and SnO 2 ). 28–48 These materials have demonstrated considerable potential for applications in gas sensing due to their chemical as well as physical characteristics, which are dependent on their thickness. 49–54 Following large-scale growth and tuning of structural characteristics, these materials' unique adaptabilities have led to a variety of uses in the fields of optoelectronic devices, electromechanical capabilities, etc.…”
