Phosgene-free photocatalytic Degradation of TCE and PCE Vapors with Au/TiO2 |
| 초록 |
Although halogenated organic compounds were widely used in industry, they are considered to be very dangerous environmental pollutants. Trichloroethylene (TCE) have been widely used in dry cleaning, metal degreasing and as chemical intermediates, therefore they are easily found in environment. Due to its high toxicity and volatility, TCE may be removed by activated carbon and air stripping, which do not degrade them but relocate it in another environment. In recent years, photocatalytic oxidation with TiO2 powder to destroy organic pollutants form contaminated water has received considerable attention and extensively been studied. TiO2 powder has, however, some detrimental shortcomings for practical application. TiO2 powder in not only difficult to be separated from water after being used, but also reduces photocatalytic efficiency due to light scattering. In this study TiO2 was coated mainly at the interior surface of glass reactor and this TiO2-coated glass reactor was employed for the photocatalytic decomposition of TCE and PCE. |
