Abstract: C1.00119 : Precision Bandgap Control of Titanium Dioxide Nanoparticles by Ultrasonication
Author:
TiO2 is a commonly used material in many areas of industry
including photocatalysis and pigments. Band gap narrowing and
particle size are engineered with a high level of control. We
report precision bandgap control by ultrasonication in novel
stable solvent systems in which unmodified TiO2 can be suspended.
The effects of ultrasonication in these unique solvent systems
are monitored by optical band gap (UV-Vis), scanning electron
microscopy (SEM), atomic force microscopy (AFM), and x-ray
diffraction (XRD).
