Abstract

Herein we show that heating 2D Ti₃C₂ in air results in TiO₂ nanocrystals enmeshed in thin sheets of disordered graphitic carbon structures that can handle extremely high cycling rates when tested as anodes in lithium ion batteries. Oxidation of 2D Ti₃C₂ in either CO₂ or pressurized water also resulted in TiO₂–C hybrid structures. Similarly, other hybrids can be produced, as we show here for Nb₂O₅/C from 2D Nb₂C.
