TiO2 has been studied in extensive applications such as photocatalysis,photovoltaics,biocompatibility,and sanitary disinfection.Non-thermal plasma (NTP) is highly efficient for synthesizing nano-TiO2 photocatalysts,but it has mainly been low pressure incorporated with sophisticated discharge and vacuum systems that have been adopted.Thus,in recent years,atmospheric-pressure NTP has been explored to synthesize nano-TiO2 powder and film photocatalysts.In this work,atmospheric-pressure linear NTP (generated by wire-to-plate dielectric barrier discharge) was employed to deposite uniformly TiO2 photocatalytic films on a moving substrate,using TiCl4 and O2 as the precursors.The tuning effect of N2 on the deposition of TiO2 films was reported.The uniformity of the as-deposited TiO2 films was investigated by SEM and UV-Vis absorption spectra.
