Comparative study of photo- and thermal catalytic hydroxylation of phenol with H2O2 over TS-1
The hydroxylation of phenol into catechol (CAT) and hydroquinone (HQ) with hydrogen peroxide and TS-1 catalyst was carried out via both photo- and dark (thermal) reactions. The conversion of phenol and the product ratio of CAT/HQ in the photocatalytic reaction were higher than those in dark (thermal) reaction.
