Until now, MXenes could only be produced from MAX phases containing aluminum, such as Ti 3 AlC 2 . Here, we report on the synthesis of Ti 3 C 2 (MXene) through selective etching of silicon from titanium silicon carbide—the most common MAX phase. Liters of colloidal solutions of delaminated Ti 3 SiC 2 ‐derived MXene (0.5–1.3 mg mL −1 ) were produced and processed into flexible and electrically conductive films, which show higher oxidation resistance than MXene synthesized from Ti 3 AlC 2 . This new synthesis method greatly widens the range of precursors for MXene synthesis.
