| Outline of Final Research Achievements |
W-doped MXene nanosheet has been prepared from W-doped MAX precursors by the selective etching. It is elucidated that doped W preferably occupies the Ti site that is exposed to the surface when converted to MXene. Formation of titanium carbonitride with a lamellar structure by heating MXene in nitrogen atmosphere has been investigated. It is elucidated that the lamellar titanium carbonitride is formed via the three steps reactions including: desorption of the surface functional groups; transformation of MXene into titanium carbonitride; and its recrystallization. Sulfur-carbon compound with amorphous structure has been synthesized by selective extraction of titanium from Ti2SC MAX and applied to a cathode of Na-ion battery.
