Abstract

The photocatalytic decomposition of 4-chlorophenol with a Keggin-type heteropolytungstate, PW<sub>12</sub>O<sub>40</sub><sup>3−</sup> (abbreviated as PW<sub>12</sub><sup>3−</sup>), under aerated conditions has been investigated in an aqueous or water-acetonitrile solution by using a 300 W Xe arc lamp at 303 K. The kinetics of the reaction indicated that the reaction proceeds via a Langmuir–Hinshelwood (or Michaelis–Menten) type mechanism, in which the complexation between the heteropolyanion and 4-chlorophenol exists as a pre-equilibrium step. This complex formation was evidenced by the observation of a new band at <i>λ</i> < 650 nm and the enhancement of the solubility of 4-chlorophenol in water in the presence of PW<sub>12</sub><sup>3−</sup>. The intensity of the new band varied in parallel with the reaction rate, depending on the concentrations of 4-chlorophenol and acetonitrile. This fact was consistent with the mechanism proposed.
