| Abstract: | The selective H2O2 oxidation reaction of phenol on LaTiO2 catalyst for catechol was investigated and the selectivity was increased by 90% comparing with that of bare titania catalyst. The effects of solvent, reaction temperature and time, concentration of hydrogen peroxide and ratio of feed upon reaction were discussed. |
