Zinc oxide thin film has an excellent optical and structural properties with wide band gap of 3.37eV. In addition, ZnO has unique photocatalytic and antiviral properties because of their high production of thereactive oxygen species which can kill the virus efficiently. In order to improve the antivirus property, the ZnOfilm with novel structures and low cost are becoming very important for development. However, there are stillcritical issues on the principal of antivirus using ZnO as well as the synthesis method is complex. In this research,we focused on the synthesizing of ZnO thin film using low cost mist CVD method, the structural andphotocatalytic properties will be investigated.
