Abstract: Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with well-defined size distributions were obtained. The particles were characterized using dynamic light scattering (DLS), electrospray-scanning mobility particle sizer (ES-SMPS), transmission electron microscopy (TEM), and X-ray diffraction (XRD) in order to gain information about the... more
