| 中文摘要 | Effect of adsorption mode on photodegradation of H-acid in TiO2 suspension was studied using DFT calculation, UV-Vis spectroscopy, FTIR, and ionic chromatography. At pH 2.5, H-acid was adsorbed on TiO2 surfaces by one dissociated sulfonic group. The adsorbed sulfonic group was attacked by surface center dot OH, resulting in the production of SO42- and the cleavage of the naphthalene ring. At pH 5.0, H-acid was adsorbed on TiO2 surfaces by two sulfonic groups. The two adsorbed sulfonic groups were simultaneously attacked by surface center dot OH, leading to a faster initial production of SO42- and initial degradation rate of H-acid than those under pH 2.5. Microscopic adsorption structures may be more important than adsorption amount in controlling the photodegradation pathways of organic pollutants. |
