Multi Layer Niobium Carbide MXene Phase Powder (Nb₂CTₓ Multi-Stacked Flakes)

Description

Multi Layer Niobium Carbide MXene Phase Powder (Nb₂CTₓ Multi-Stacked Flakes)

This layered niobium carbide MXene (Nb₂CTₓ) powder is a black, plate-like material composed of multi-stacked MXene flakes with micron-scale dimensions. The particles exhibit lateral lengths of approximately 10–25 µm and an average lateral width around 28 µm, forming a high-surface-area structure ideal for advanced material development.

Thanks to its multi-layer morphology, this Nb₂CTₓ MXene provides excellent electrical conductivity, tunable surface chemistry, and strong interfacial interaction, making it suitable for use as a precursor, conductive filler, or functional additive in electronic, catalytic, and composite systems. Its robust structure and large accessible surface area make it a versatile material for next-generation research and industrial innovation.

What This Material Is

Nb₂CTₓ belongs to the MXene family—two-dimensional transition-metal carbides and carbonitrides derived from selective etching of MAX phase precursors. Multi-layer Nb₂CTₓ consists of stacked nanosheets rather than fully delaminated flakes, offering greater mechanical stability and high loading capacity in composite formulations.

Applications 

Energy Storage Devices

Layered Nb₂CTₓ acts as a conductive, high-surface-area additive for battery and supercapacitor electrodes, improving charge transfer, surface activity, and electrode–electrolyte interface performance. It also serves as a precursor for engineered MXene-based electrode structures.

Electrocatalysis & Catalyst Supports

Its large active surface and conductive nature make multi-layer Nb₂CTₓ an excellent support material for catalytic nanoparticles in HER, OER, ORR, and CO₂-reduction reactions, enhancing efficiency and electron transport pathways.

Conductive Inks & Printed Electronics

After dispersion or partial exfoliation, Nb₂CTₓ can be formulated into conductive inks, pastes, and coatings, suitable for flexible circuits, EMI-shielding tracks, printed sensors, and stretchable electronics.

Composite Reinforcements

As a filler in polymer, ceramic, or metal matrices, Nb₂CTₓ significantly enhances electrical conductivity, thermal transport, and mechanical strength, enabling applications in antistatic coatings, thermal interface materials, and high-performance structural composites.

Sensing & Detection Platforms

The high surface area and customizable surface terminations (Tₓ groups) support chemiresistive, electrochemical, and biosensing devices. Functionalization enables high selectivity for target gas or biomolecule detection.

Surface Functionalization & Hybrid Material Synthesis

Nb₂CTₓ is commonly used as a base material for chemical grafting, heterostructure formation (with metals, oxides, or other 2D sheets), and layer-by-layer assembly, enabling precision tuning of surface or electronic properties.

Electromagnetic Interference (EMI) Shielding

When incorporated in polymer or resin systems, layered MXene flakes form conductive pathways that attenuate electromagnetic radiation across microwave and radio frequencies.

Templates & Precursors for Advanced Architectures

Multi-layer Nb₂CTₓ can act as a template or sacrificial scaffold for producing porous carbides, oxides, and derived composite nanostructures through controlled thermal processing.

 Production Overview 

Nb₂CTₓ MXene is typically produced by selectively etching the “A-layer” from a niobium aluminum carbide MAX phase (Nb₂AlC). Acidic or fluoride-containing etchants remove the Al layer, leaving behind layered Nb₂CTₓ sheets. The final product is then washed, neutralized, and dried to obtain a multi-layer stacked MXene powder with preserved flake morphology.
