Preparation and antibacterial activity studies of $\rm TiO_2$ nanostructured materials
Аннотация
Different morphologies of nanostructured $\rm TiO_2$ materials can be tailor-made as a function of growth time varied from $1$ to $7$ h with a step of $2$ h. $\rm TiO_2$ nanostructures were prepared on titanium foil by a facile water-assisted chemical vapor deposition method at $850^{\circ}$C. Scanning electron microscopy examination of the samples reveled that, under the treatment time of $7$ h, the morphology of nanostructures transformed from cubic nanostructure-like to agglomerated nanorod-like and nanoplate shape. The X-ray diffraction through synthesized $\rm TiO_2$ nanostructures exhibited the crystalline structure of rutile $\rm TiO_2$ formed during the synthesis process. X-ray diffraction analysis showed that at deposition time of $7$ h the intensity peak of $[110]$ plane strongly decreased and seems that the $[210]$ plane peak is the preferred orientation at this condition. Present paper deals with studies of the antibacterial activity of different synthesized samples after $24$ h in the presence of Escherichia coli and Staphylococcus aureus cells. It is found that the growth time has an essential role in the morphology and antibacterial properties of $\rm TiO_2$ nanostructures.
