We oxidized two-dimensional Ti₃C₂, also known as “MXene” in air under two different oxidizing regimes in order to produce carbon-supported TiO₂. Furthermore, the in situ TEM analysis coupled with Raman spectroscopy revealed the formation of either anatase nanoparticles or planar rutile nanocrystals, which were controlled by the time, temperature and heating rate.
