Rutile powder was synthesized via sol–gel processing of T yzor TE precursor in an aqueous solution at 40°C–50°C. A suite of characterization techniques, including FTIR , R aman, X ‐ray, and electron diffraction, were employed to investigate the microstructural evolution. The synthesized powder was phase‐pure rutile possessing high surface area (144.7 m 2 /g), an average pore size of 24.9 nm, and pore volume of 0.66 cm 3 /g. A reaction mechanism is proposed for the preferential evolution of rutile over other titania polymorphs (i.e. amorphous or anatase).
