Multilayer/Monolayer Nb₄C₃T_x

Molecular Formula: Nb₄C₃T_x

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

Product Introduction

Multilayer and monolayer Nb₄C₃T_x, a member of the MXene family, are advanced two-dimensional materials. These materials feature a layered structure with Nb₄C₃ at their core and surface terminations (T_x), such as hydroxyl, oxygen, or fluorine, that result from chemical etching processes. The multilayer variant consists of stacked Nb₄C₃ sheets, while the monolayer (few-layer) form consists of flakes with ≤5 layers. Both forms exhibit exceptional properties. These attributes make Nb₄C₃T_x materials highly valuable for applications in energy storage, catalysis, electromagnetic shielding, and sensing technologies.

Alfa Chemistry's Nb₄C₃T_x is etched from the precursor phase Nb₄AlC₃. Currently, the most commonly used etching method is hydrofluoric acid (HA) etching. Our team of experts has introduced etching-perfected preparation solutions while ensuring material stability.
