Titanium dioxide (TiO2
) with various morphologies has been successfully synthesized by a simple hydrothermal method
at 150o
C for 10 h using titanium butoxide (TBOT) as a precursor, deionized (DI) water and hydrochloric acid (HCl) on
a fluorine-doped tin oxide (FTO) substrate. The influences of HCl volume on structural and morphological properties
of TiO2
have been studied using x-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM),
respectively. The result showed that several morphologies such as microsphere, microrods, nanorods and nanoflowers
were obtained by varying the volume of hydrochloric acid. The crystallinity of titanium dioxide enhanced with the
increasing of hydrochloric acid volume.
Titanium dioxide (TiO2
) nanorods and nanoparticles had been successfully done by hydrothermal method and spray
pyrolysis deposition technique, respectively. Form XRD results, crystallite structure for TiO2
nanorods is rutile phase
at 2θ degree 27.5° which corresponded to [110] orientation. Whereas, TiO2
nanoparticles produced anatase phase at
2θ degree 25.3° which corresponded to [110] plane. The structure of nanorods and nanoparticles were characterized
using FESEM. The size of nanorods was in the range of 80 to 100 nm. While, the nanoparticles size was ranging from
25 to 35 nm. The HeLa cells were grown on those TiO2
and were observed under fluorescence microscope. The cells
showed healthy sign of growth on TiO2
nanorods and nanoparticles substrates. Thus, TiO2
nanorods and nanoparticles
are biocompatible to HeLa cells.
