Low Cost Synthesis Method of Two-Dimensional Titanium Carbide MXene

A layered MAX phase of Ti3AlC2 was synthesized through pressureless sintering (PLS) the initial powder of TiH2/Al/C without preliminary dehydrogenation under argon atmosphere at 1350 degrees C. An elegant exfoliations approach was used to prepare a two-dimensional (2D) metal carbide Ti3C2 from layered MAX phase by removing A layer by chemical etching. The use of PLS method instead of any pressure assistance method such as hot isostatic press (HIP) and hot press (HP) lowered the cost of synthesis. Recently, some unique potential of Ti3C2 has been discovered leads to the proposal of potential application, mostly on electronic devices. Morphology and structural analysis was used to confirm the successful of this research.
