The synthesis of Ti3C2Tx (and Ti2CTx alike) MXenes is performed with a new etching environment (FeF3/HCl). Significant differences in terms of surface functionalization (including the insertion of iron cations between the MXene sheets), morphology, nature of impurities, water intercalation and reactivity are obtained in comparison with samples prepared by conventional HF or LiF/HCl etching methods. In particular, the new synthesis method allows modifying the reactivity of Ti3C2vs. water with… Expand
