摘要
The gas phase photocatalytic degradation of trichloroethylene (TCE) was studied over two kinds of TiO2, as thin films prepared by the sol-gel process. Dichloroacetyl chloride (DCAC), phosgene and carbon monoxide were confirmed to be intermediates, The detection conditions of DCAC, a main but unstable intermediate, were investigated in different experimental conditions by using in situ FTIR measurement and gas chromatography. Reaction intermediates were different depending on the activity of the photocatalyst. (C) 1997 Elsevier Science Ltd.
