Abstract

Self-assembling has been confirmed as an effective pathway to achieve some unique properties. The recently developed two-dimensional transition metal carbides (termed MXene) provide more potential opportunities to modify the surfaces of layered materials relative to simple graphene. Here we describe a one-step method for preparing an urchin-like rutile TiO2–C (u-RTC) nano-composite with a high amount of (110) facets by in situ phase transformation of MXene (Ti3C2(OH)0.8F1.2) under FeCl3 conditions. A layered anatase TiO2–C (l-ATC) nano-composite with a high percentage of (001) facets first forms, and then it changes into u-RTC due to the Fe(III) ion induction. The u-RTC displays a high Cr(VI) adsorption capacity of ∼225 mg g−1, which is higher than that of the primitive MXene (∼62 mg g−1) and the l-ATC precursor (∼11 mg g−1), owing to the inhibition of H2O molecule adsorption by bridging oxo groups in terms of the first principles calculations. Apart from the fact that the finding leads to a desirable aligned oxide-carbon material, this approach may set up a new trajectory to self-assemble functional surfaces of other MXene derivatives.
