Synthesis of urchin-like rutile titania carbon nanocomposites by iron-facilitated phase transformation of MXene for environmental remediation

A novel 2D material is prepared by in situ phase transformation of layered MXene with the induction of Fe( iii ) ion. The urchin-like rutile TiO ₂ –C nanocomposite with a high amount of (110) facets exhibits a high Cr( vi ) adsorption ability of ~225 mg g ⁻¹ , which is the highest value based on a simple adsorption mechanism reported so far
