产品概述

MXenes (Transition Metal Carbon/Nitride 2D Material)

MXenes are a class of two-dimensional transition metal carbides, nitrides, or carbonnitrides obtained by selective etching of layers A 

(usually Al, Si, etc.) by MAX phase precursors with the general formula Mn₊₁XnTₓ (where M is the transition metal, X is C and/or N, and 

Tₓ represents surface end groups such as –O, –OH, –F, etc.). Thanks to its metal-grade conductivity, layered structure, high specific

surface area, and rich and adjustable surface functional groups, MXenes has demonstrated unique advantages in the fields of energy storage and conversion, electromagnetic functional materials, sensing and environmental governance, and has become one of the fastest growing 2D material systems in recent years.


(1) Electrochemical energy storage and energy conversion: In the field of electrochemical energy storage, MXenes is particularly 

suitable for supercapacitor electrode materials, and its pseudocapacitor/electric double-layer capacitor synergy mechanism gives it 

high volume capacitance, excellent rate performance, and rapid charging and discharging capabilities. Compared with traditional 

carbon materials, MXenes' interlayer intercalation properties and surface functional groups facilitate the rapid transport and reversible adsorption and desorption of electrolyte ions. In addition, MXenes exhibits good rate performance and cycle stability as anode materials in lithium-ion, sodium-ion, potassium-ion, and other metal-ion batteries, and its energy storage mechanism usually involves the synergy of ion embedding, surface adsorption, and pseudocapacitance behavior. In terms of energy conversion, MXenes is also widely used in electrocatalytic reactions such as hydrogen evolution, oxygen evolution, and CO₂ electroreduction, often as intrinsic catalysts or highly conductive supports, and its surface end group and electronic structure can effectively regulate the adsorption behavior of reaction intermediates.


(2) Electromagnetic shielding and conductive composites: With its excellent intrinsic conductivity and high aspect ratio sheet

 structure, MXenes demonstrates significant advantages in the field of electromagnetic interference (EMI) shielding. By constructing 

multi-layer stacked structures or compounding with polymers and carbon materials, MXene-based materials can achieve efficient 

electromagnetic wave reflection and absorption while maintaining lightweight and flexibility, making them potentially suitable for 

flexible electronic devices and aerospace. At the same time, MXenes can significantly improve the conductivity and interfacial charge transfer ability of composites as a conductive filler.


(3) Sensing and flexible electronics: MXenes has a highly sensitive electrical response to gas molecules, biomolecules and ions, and 

its sensing performance comes from the interaction between surface functional groups and target molecules and the resulting 

electrical conductivity changes. As a result, MXenes has been used to build gas sensors, biosensors, and flexible wearable sensor 

platforms. In flexible electronics, MXenes' solutionability and good mechanical flexibility make it suitable for integration into 

flexible substrates for highly sensitive and fast-response signal detection.


(4) Environmental treatment, functional coatings, and other applications: In terms of environmental treatment, MXenes' high 

specific surface area and adjustable surface chemistry make it potentially valuable in water treatment, ion adsorption, and 

pollutant removal. Additionally, MXenes is being explored for use in lubricating materials, anti-corrosion coatings, and transparent 

conductive films, where its layered structure contributes to reducing the coefficient of friction, while its high conductivity and 

optical tunability open up possibilities for its application in transparent electrodes. It should be pointed out that MXenes still faces 

challenges such as oxidation stability and large-scale preparation in practical applications, which is also the focus of current 

research.
