Our new collaborative research paper with Drexel team on Porous Ti3AlC2 MAX phase enables efficient synthesis of Ti3C2Tx MXene

Our new collaborative research paper with research group from Drexel University on Porous Ti3AlC2 MAX phase enables efficient synthesis of Ti3C2Tx MXene:

MXenes, a large family of 2D carbides and/or nitrides, are amongthe most studied materials worldwide due to their great diversity of structuresand compositions. Their unique properties find use in several applications. Typically, they are manufactured by selective wet-chemical etching of layered MAXphase ceramics, which are produced nowadays primarily for MXene synthe-sis. However, the synthesis of MAX phases has not been changed since the time of their use in structural and high-temperature applications, and it has not been optimized for MXene manufacturing. In this study, we have optimized the synthesis of MAX phases for MXene manufacturing.

porous MAX phase sintering Ti3AlC2

 The main purpose of this study is 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 titanium sponge instead of a highly pure titanium powderand explain the mechanisms of reaction sintering and formation of porous MAXphase. MXene obtained from this MAX phase, Ti3C2Tx, shows larger flake sizeand higher electrical conductivity in thin films, compared to the materials pro-duced from the costly fine titanium powder. The proposed approach may applyto the synthesis of other MAX phases as well.
