We demonstrate a quantitative relationship between exposed (001) crystal surfaces and photocatalytic activity of nanocrystalline films prepared by DC magnetron sputtering that follow a square dependence.

Experimental Conditions

Experimental conditions to fabricate rutile-TiO2 nanotubes coated with a conformal anatase-TiO2 thin layer using ALD were reported. A considerable increase in the photocatalytic activity associated with these surface modifications was also observed.

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.
