V4C3Tx MXene Phase Powder Description

V4C3Tx MXene phase powder is a novel two-dimensional transition metal carbide material synthesized by selectively etching the aluminum layers from its parent V4AlC3 MAX phase, typically using hydrofluoric acid or fluoride-containing etchants, which results in surface functionalization denoted by “Tx” (such as -O, -OH, -F groups). This process yields a multilayered powder composed of accordion-like particles with a high specific surface area, excellent metallic conductivity, and inherent hydrophilicity. The material demonstrates remarkable electrochemical properties, including high volumetric capacitance, making it a promising candidate for advanced energy storage devices like lithium-ion batteries and supercapacitors. Furthermore, its unique layered structure, mechanical robustness, and tunable surface chemistry also render it suitable for applications in electromagnetic interference shielding, catalysis, gas sensing, and composite reinforcement. The performance of V4C3Tx powder is highly dependent on synthesis parameters, etching conditions, and post-processing techniques, which control its defect density, flake size, and termination groups.
