摘要：
The photodegradation reaction rate of 4-chlorophenol (4-CP) with a titanium silicalite -2 (TS-2) catalyst is found to be faster in the initial stage than with TiO2. This is primarily due to the stronger adsorption of 4-CP on the hydrophobic surface of the TS-2 catalyst. The hydrophobicity is evaluated by determining the distribution coefficients (D) between TS-2 and aqueous medium using a variety of aromatic hydrocarbons. The larger the D, the faster the initial reaction rate. The D correlates with solubility in water and partition coefficient, log P-oct.
