Recent Advancement for the Synthesis of MXene Derivatives and Their Sensing Protocol

Abstract

sensing discipline and plays an indispensable role in many different research and applications. [2] During last decade various sensing techniques such as electrochemistry, [3] electronics, [4] optics (fluorescence, absorbance, chemiluminescence, surface plasmon resonance, and Raman spectra) [5] were successfully applied by different researcher worldwide. [6] However, it is still a major challenge to satisfy the rising demand for sensing with low price characteristics, the high value of sensitivity, and convenient service. [7] Due to unique optical and electrochemical properties over the past decade, different morphologies of 0D, 1D, and 2D materials are successfully applied to achieve more efficient results.In the visible region, metallic-based 0D and 1D materials, the most widely explored metal nanostructures, have different plasmonic absorption bands. The absorption peak of metallic NPS is extremely sensitive to even minor variations in the environment's dielectric properties. [8] The interactions between an electric field and a radio frequency-like laser pulsed field could also enhance the optical processes such as surface-enhanced Raman scattering (SERS). There are numerous publications in which the production of metallic NPs for plasmonic sensing has been addressed. [9] However, the metallic NPs have certain notable disadvantages, such as high cost, poor stability, and adsorption ability toward chemicals or biomolecules, thus, hampering its application in plasmonic sensing.The highly efficient, 2D material-based sensing devices are well-suited with the advanced production technology, which provides the data that can be applied effectively for the monitoring of environmental and health-related problems.Various 2D material like transition metal chalcogenides, graphene and its oxides, metal oxides black phosphorus (BP), and some other 2D nanomaterials are representing the prosperities to be alluring for the preparation process of highly sensitive sensors because of their exceptional material characteristics which arise from their inherent structures. [10] The main benefits of features like energy-efficient, miniaturization, low-cost, easy production, online monitoring system, and simultaneous sensing capability are the driving force for the continued The highly efficient, 2D material-based sensing devices are well-suited with the advanced production technology which provide the data that can be applied effectively for the monitoring of environmental and health-related problems. Recently, MXenes considered as new blood in the form of 2D transition metal carbides (TMC), transition metal nitride or transition metal carbonitrides that are added first time to 2D nanomaterials family MXene which are compounds obtained as a result of chemical delamination of quaternary or (ternary) layered nitrides or carbides found as an outstanding member of 2D elemental materials. On behalf of rich chemistries and unique morphologies, the MXenes derivatives delivered efficient sensors, energy storage, catalysis, and water purifica...

A Family of 2D-MXenes: Synthesis, Properties, and Gas Sensing Applications

“…Even though there are many research papers on MXenes, the key aspects have been summarized in informative review articles − and books . In addition, a few overviews of MXene-based gas sensors have been reported. ,− However, no comprehensive review has focused on recent developments in the MXene gas sensors for potential applications. This review systematically describes the summary of a diverse range of MXenes and their synthesis methods.…”

Applications of MXenes in human-like sensors and actuators

“…The saturable absorber properties of MXenes [327][328][329] have been employed for applications of pulsed laser [330,331], soliton pulses [332], optical modulators [333][334][335], wavelength conversion [336], and integrated photonic circuits [103,337,338]. Besides, MXenes have been incorporated into optoelectronic devices such as photovoltaic cells [91,339] and photodetectors [23,97] as carrier transport layers and heterojunction contact [24].…”

Superconductivity in monolayer Ba$_2$N electride: a first-principles study

“…As for MXene, both experiment and theory suggest that it is an ideal kind of material for discovering superconductors. However, until now, very few nitride MXenes have been synthesized 71,72 and among them only Mo 2 N was predicted to be superconducting with a T c of 16 K 34 . The phonon properties of Mo 2 N and Ba 2 N are quite different.…”
