SEM and XRD analyses confirm morphology and crystal structure of three TiO
nanoparticles differing in geometric dimension. A, Image of titanium dioxide nanospheres (NS) 60-200 nm in diameter. B, Image of titanium dioxide short nanobelts (NB-1) 60-300 nm in diameter and 0.8-4 μm in length. C, Image of titanium dioxide long nanobelts (NB-2) 60-300 nm in diameter and 15-30 μm in length. D, XRD patterns of all three titanium dioxide nanoparticles stacked. The data was consistent with all three nanoparticles exhibiting anatase structure.
