Description

General description

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

Application

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.
