Background: Since MXenes' discovery, obtaining porous MAX phase precursors, such as Ti3AlC2, for the synthesis of MXenes, such as Ti3C2, became an important task. The low-density MAX phase can be crushed into powder with little force and without extensive milling. This not only decreases the cost of manufacturing, but also avoids lattice distortion of the MAX phase and produces a higher quality MXene. Conventionally, MAX phases are produced by hot pressing, hot isostatic pressing, or pressureless sintering, as they were developed for structural applications requiring dense and mechanically strong materials. All those methods lead to hard and strong sintered bodies that require crushing and high-energy milling to produce a powder. A traditional approach to manufacturing porous Ti—Al—C and some other ceramics is to add different additives in the mixture such as NaCl that prevent complete sintering and can be removed during or after processing. However, any addition to the mixture can lead to contamination of the MAX phase and MXenes, as well as affect the stoichiometry, purity, and properties of the materials.
In this work we have optimized the synthesis of MAX phases for MXene manufacturing. The main purpose was to develop a porous Ti3AlC2MAX phase that can be easily ground into individual grains manually without time-consuming eliminating the need for drilling and intenseball-milling before MXene synthesis. Moreover, we also demonstrate the synthesis of highly porous Ti3AlC2 (about 70%) from an inexpensive raw materials.

MXenes potential applications include sensors, wound healing materials, and drug delivery systems. A recent study explored how different synthesis methods affect the safety and performance of MXenes. By comparing etching conditions and intercalation strategies, researchers discovered that fine-tuning the surface chemistry of MXenes plays a crucial role in improving biocompatibility. These results provide practical guidelines for developing safer MXenes and bring the field one step closer to real biomedical applications.
