Mo2CTx MXene Phase Powder Description
Mo₂CTₓ MXene Phase Powder is a two-dimensional molybdenum carbide material belonging to the MXene family, synthesized by selectively etching the aluminum (Al) or gallium (Ga) layer from its precursor MAX phase, typically Mo₂GaC or Mo₂AlC, using fluoride-based etchants. The resulting structure consists of atomically thin layers terminated with functional groups such as -O, -OH, and -F, collectively denoted as Tₓ. These surface groups grant the material hydrophilicity, tunable electronic properties, and enhanced chemical reactivity. Mo₂CTₓ exhibits high metallic electrical conductivity, good mechanical flexibility, and notable chemical stability. Due to its rich surface chemistry and high surface area, it shows great promise in applications including high-performance supercapacitors and battery electrodes, efficient electrocatalysts for hydrogen evolution and nitrogen reduction reactions, electromagnetic interference (EMI) shielding composites, sensors, and functional coatings. Its molybdenum-rich composition further contributes to its enhanced electrochemical activity and stability in demanding environments.
