MXene
We produce advanced MXenes—2D transition metal carbides, nitrides, or carbonitrides—that combine metallic conductivity, hydrophilicity, and tunable surface chemistry for cutting-edge applications. Synthesized by selectively etching the A-layer from MAX phases, our MXenes offer exceptional performance in energy storage, catalysis, and beyond.
Technical Properties
Mₙ₊₁XₙTₓ (M = early transition metal such as Ti, V, Nb, Mo; X = C or N; Tₓ = –OH, –O, or –F surface terminations).
Produced by etching A-layer from MAX phases (Mₙ₊₁AXₙ, with A typically being Al or Si); common methods include HF etching, with alternative fluoride-free methods (LiF-HCl, molten salt, electrochemical) available.
Layered structure akin to graphene, but with higher metallic conductivity (~6000 S·cm⁻¹) and intrinsic negative charge, which facilitates stable aqueous colloidal suspensions.
High volumetric capacitance (~900 F·cm⁻³) and large surface area (~200–300 m²·g⁻¹) that enhance charge storage and ion diffusion.
Products and Applications
MXenes are ideally suited for electrochemical energy storage, including Li-ion and Na-ion batteries, where their fast charge transfer kinetics and structural stability yield high-rate performance and long cycle life. Their high conductivity and abundant redox-active sites also make them excellent catalysts for oxygen reduction (ORR) and hydrogen evolution reactions (HER). Additionally, MXenes excel in electromagnetic interference (EMI) shielding, outperforming traditional carbon-based materials in this arena.
