Descrizione generale

4-Chlorophenol undergoes dechlorination to phenol rapidly on palladized graphite electrodes. Mechanism of 4-chlorophenol oxidation has been investigated by radiolytic and photocatalytic techniques.

Applicazioni

4-Chlorophenol was used:
  • As a substrate in the visible-light-induced degradation studies of phenolic compounds in an aqueous suspension of pure TiO2.
  • As a model chlorinated organic pollutant in the hydrodechlorination studies of phenols using palladium nanocrystal catalysts.
  • To prepare 4-chlorocatechol, hydroquinone, and benzoquinone via photo mineralization using Degussa P25 TiO2.

The visible-light-induced degradation reaction of 4-chlorophenol (4-CP) was investigated in aqueous suspension of pure TiO2. Contrary to common expectations, 4-CP could be degraded under visible illumination (lambda > 420 nm), generating chlorides and CO2 concomitantly. The observed visible reactivity was

Magnetic nanoscaled Fe(3)O(4)/CeO(2) composite was prepared by the impregnation method and characterized as a heterogeneous Fenton-like catalyst for 4-chlorophenol (4-CP) degradation. The catalytic activity was evaluated in view of the effects of various processes, pH value, catalyst addition, hydrogen peroxide
