TiO2/Ti2−yVyCTx heterostructures are derived from double transition metal (Ti, V) MXenes through in situ selective oxidation. With the catalyze of oxygen and water molecules, Ti atoms are preferentially oxidized and transformed into TiO2, while V atoms with higher oxidative tolerance can maintain th...
