Selective Etching of Silicon from Ti3SiC2 (MAX) Produces 2D Titanium Carbide (MXene)

Congratulations to Mohamed, Kathleen, Tyler, Asia, Christine, Simge and Ariana on publication of their paper that describes synthesis of Ti3C2 MXene by etching Ti3SiC2.  This was the first MAX phase we attempted to etch about 7 years ago, but didn’t initially succeed. Finally, Mohamed accomplished the task using the oxidation/etching technique that my student Goknur Cambaz previously applied to selective etching of SiC whiskers. He further developed and optimized it showing that a large variety of oxidants can be used. Now, we know that not only aluminum can be etched away from MAX phases to produce MXenes. Congratulation on this accomplishment!
