摘要: As one of the typical indoor pollutants, formaldehyde has attracted more and attention. It is well known that long-term exposure to even fairly low levels will bring risk asthma, eczema other diseases. In this study, nano-TiO2/β-cyclodextrin (β-CD) coated paper was applied remove under UV irradiation. The optimum composition nano-TiO2/ β-CD on studied in detail with regard efficiency removal. results showed gaseous can be removed by nano-TiO2/β-CD different efficiencies depending upon ratios nano-TiO2 paint. After 6 h irradiation, completely papers ratio 1 3. could decompose repeatedly after regeneration. This kind used as air-cleaning materials such wallpaper various pollutants indoor.
