In this study, the nano-TiO2/ZnO coated paper was applied to remove formaldehyde in the air. In order to improve photo-catalytic efficiency of titanium dioxide (TiO2), another semiconductor with different band gap, such as zinc oxide (ZnO), was compounded with TiO2 together. The complex of nano TiO2/ZnO was then coated on the paper. The behavior of photo catalytic decomposition of formaldehyde by the coated paper under UV irradiation and natural light was investigated. The ratio of nano-TiO2 and ZnO for the removal of indoor pollutants was studied in detail. The results showed that the paper coated with ZT-20 was more effective for the photo-catalytic decomposition of formaldehyde than the paper with TiO2 only.
