Abstract

TiO

$_2$ thin films are used for oxidation of organic radicals, reducing CO

$_2$ , skin cancer treatment, decomposing halogen compounds in the air, breaking down surface contaminants, water treatment, biodegradable oil on the surface of the water, disinfect, anti-bacteria, self-cleaning and anti-fog coating,… To increase the photocatalytic and anti-Ecoli bacteria abilities of TiO

$_2$ thin films, this study synthesized the ZnO/TiO

$_2$ hierarchical heterogeneous nanostructures (HNs) by DC magnetron sputtering. The results showed that ZnO/TiO

$_2$ (HNs) has been the photocatalytic and anti - Ecoli bacteria abilities higher than TiO

$_2$ film. This result is explained by reducing the recombination of electrons - holes and slightly shifted absorption edge of them to the visible light band.
