3D hierarchical Ti3C2/TiO2 composite via in situ oxidation for improved lithium-ion storage

Abstract

To address the intrinsic limitations of both TiO₂ and MXenes, we propose an effective strategy for the engineering of a 3D Ti₃C₂/TiO₂ nanorod hybrid, where the in situ synthesized TiO₂ nanorods are homogeneously decorated onto the surface of 3D Ti₃C₂ MXene via simple oxidation. As the LIB anode, it demonstrates exceptional long-term cycling stability with a specific capacity of 384.1 mA h g⁻¹ after 600 cycles at 1.0 A g⁻¹.
