High-temperature stability in air of Ti₃C₂T_x MXene-based composite with extracted bentonite.

ABSTRACT: Although Ti₃C₂T_x MXene is a promising material for many applications such as catalysis, energy storage, electromagnetic interference shielding due to its metallic conductivity and high processability, it's poor resistance to oxidation at high temperatures makes its application under harsh environments challenging. Here, we report an air-stable Ti₃C₂T_x based composite with extracted bentonite (EB) nanosheets. In this case, oxygen molecules are shown to be preferentially adsorbed on EB. The saturated adsorption of oxygen on EB further inhibits more oxygen molecules to be adsorbed on the surface of Ti₃C₂T_x due to the weakened p-d orbital hybridization between adsorbed O₂ and Ti_3<
