Pure anatase mesoporous TiO2 nanospheres were synthesized by simple wet chemical treatment and characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), ultraviolet-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (XRD). The results revealed that the surface morphology of the TiO2 spheres could be controlled by adjusting the concentration of N-methylaniline and that the average diameter of the TiO2 spheres was 600 nm. FTIR results confirmed the formation of N-methylaniline capped TiO2 nanospheres. (C) 2012 Elsevier Ltd. All rights reserved.
