Molecular Formula: Nb₂CT_x

Storage Conditions: Store refrigerated (4°C) or in a vacuum or inert environment for 2-6 months.

Product Introduction

Nb₂CT_x is a type of two-dimensional material, a member of the MXene family, composed of niobium (Nb) and carbon (C) layers, with surface terminations (T_x) that can vary, typically including oxygen, hydroxyl, or fluoride groups. These terminations play a crucial role in enhancing the material's surface properties, such as hydrophilicity and the ability to form stable dispersions in aqueous solutions.

Alfa Chemistry's Nb₂CT_x is etched from the precursor phase Nb2AlC. Currently, the most commonly used etching method is hydrofluoric acid (HA) etching. We have also introduced a lithium-ion exchange technology, which addresses the oxidation issues caused by high-temperature etching or incomplete removal of intercalants.

Product Characteristics

The product appears as a (golden) brown powder or dark blue liquid.
The concentration of the product is adjustable, and the flake size is controllable.
The liquid should be stored refrigerated (0-4 °C), while the powder should be stored in a vacuum-dried or inert environment.
