SciMater^TM MXene Powders (21 Series)

Two-Dimensional Transition-Metal Carbides | M₂X Structural Family | Ti₂C, Mo₂C, Nb₂C, and V₂C | Multiple Product Forms

The 21-series MXene portfolio includes Ti₂C, Mo₂C, Nb₂C, and V₂C two-dimensional materials with an M₂X structural framework. Available forms include multilayer powders, few-layer or predominantly single-layer powders, and selected clay-like materials. These products are suitable for electrochemical energy storage, catalysis, sensing, conductive composites, thin films, coatings, and two-dimensional interface research.

Product Overview

MXenes are a family of two-dimensional layered materials composed of transition-metal carbides, nitrides, or carbonitrides. The basic structure of the 21 series is generally represented as M₂X, where M is a transition-metal element and X is carbon. Their surfaces commonly contain terminations such as —O, —OH, and —F, and they are therefore frequently written as M₂CT_x in scientific literature.

Ti₂C, Mo₂C, Nb₂C, and V₂C differ in electronic structure, surface reactivity, electrochemical behavior, hydrophilicity, and environmental stability. Actual lateral size, thickness, layer-number distribution, surface terminations, moisture content, and oxidation state should be confirmed using batch-specific technical data.

Ti₂C

Titanium-Based 21-Series MXene

Suitable for energy storage, sensing, conductive composites, thin films, and interface regulation. It is available in the broadest range of forms within this series.

Mo₂C

Molybdenum-Based 21-Series MXene

Suitable for electrocatalysis, surface reactions, electrochemistry, and composite-material research, with several forms available for different processing routes.

Nb₂C

Niobium-Based 21-Series MXene

Suitable for electrochemistry, photothermal research, conductive composites, two-dimensional films, and functional-interface studies.

V₂C

Vanadium-Based 21-Series MXene

Suitable for ion storage, electrocatalysis, sensing, thin films, and fundamental studies of two-dimensional material properties.

Multilayer Powder Exhibits distinct stacked-layer structures, is convenient to weigh, store, and formulate, and is suitable for routine electrochemistry, composites, and subsequent delamination studies.

Few-Layer / Predominantly Single-Layer Powder Contains predominantly thinner sheets and a greater proportion of accessible interfaces, supporting thin-film, sensing, catalytic, and two-dimensional assembly research.

Clay-Like Material Supplied as a moist, viscous material for slurries, films, coatings, and gel systems, reducing the need to redisperse a fully dried powder.

Instructions for Use

01 Select the Product Form Select multilayer powder, few-layer / predominantly single-layer powder, or clay-like material according to the experimental objective, and verify the model and batch documentation.

02 Weigh and Pre-Wet Add a small amount of dispersion medium to the powder first and wet it thoroughly before gradually adding more solvent. This helps reduce agglomeration and floating powder.

03 Assist Dispersion Vortex mixing, mechanical stirring, or low-power ultrasonication may be used. Control temperature rise and avoid prolonged high-power treatment.

04 Prepare the Sample Use vacuum filtration, drop casting, spin coating, spray coating, blade coating, electrode-slurry preparation, or composite mixing as required. Record solids content and processing conditions.

05 Store and Recheck Reseal promptly and protect from light. Before reuse, check color, sedimentation, dispersion state, and signs of oxidation.

When handling dry powders, wear laboratory gloves, safety goggles, and an appropriate dust mask or respirator, and weigh the material in a fume hood or under local exhaust. For oxidation-sensitive experiments, minimize exposure to air, elevated temperature, and strong light.

Frequently Asked Questions

01What is the difference between multilayer and few-layer / predominantly single-layer powders?

Multilayer powders retain more distinct stacked-layer structures and are generally easier to store, weigh, and formulate in larger quantities. Few-layer / predominantly single-layer powders have undergone further delamination, contain thinner sheets, and provide more accessible interfaces for thin-film, sensing, catalytic, and interface-assembly research.

02Does “few-layer / predominantly single-layer” mean that every sheet is strictly monolayer?

Not necessarily. The description generally means that single-layer and few-layer sheets are the principal components; it does not mean that every sheet is strictly monolayer. Layer-number and thickness distributions should be evaluated using AFM, TEM, or other relevant characterization.

03Can MXene powder be dispersed directly in water?

A small-scale dispersion test is recommended first. Dispersion depends on surface terminations, oxidation state, concentration, temperature, and ultrasonication conditions. Pre-wet the powder thoroughly and then use stirring or low-power ultrasonication to disperse it gradually.

04How should MXene materials be stored?

Store sealed, protected from light, and with minimal exposure to air and moisture. Low-temperature or inert-atmosphere storage may be used for oxidation-sensitive experiments. Use opened material promptly and avoid repeated prolonged exposure.

05Can different models or batches be compared directly?

Direct comparison based only on chemical formula is not recommended. MXene performance is also influenced by lateral size, layer number, surface terminations, oxidation state, moisture content, dispersion method, and electrode-processing conditions. Compare materials under consistent test conditions and use batch-specific characterization data.
