Novel Fe doped mesoporous TiO2 microspheres were fabricated by an ultrasonic-hydrothermal method when tetrabutyl titanate was used as a precursor and octadecylamine was used as a structure-directing agent. The mesoporous materials were characterized by XRD, SEM, TEM, N2 adsorption-desorption measurements, XPS, FL, and UV-vis. The results suggest that both ultrasonic treatment and hydrothermal procedure are critical for the fabrication of Fe doped mesoporous TiO2 microspheres with a combination of regular morphology, large specific surface area, high crystallinity, and high thermal stability.
