The indoor air pollutants may cause adverse health effect, among formaldehyde is widely applying in the construction and decoration. It is easy to evaporate and be inhaled at room temperature, furthermore it, has been identified as a human carcinogen. In this study we synthesized titanium dioxide / polyaniline composites. The composite was tested to evaluate the formaldehyde removal with or without the UV. The results showed that the chromaticity removal rate of methylene blue by titanium dioxide / polyaniline composites with UV was over 99% for 120 minutes. Without UV light, polyaniline has the highest removal rate of 85.4%, however, it was only 52.5% for the complex T/P 1(titanium dioxide / polyaniline proportion = 1). The formaldehyde removal rate for 0.1 g of the composite T/P 1.
