| Abstract: | The selective H 2O 2 oxidation reaction of phenol to catechol on Ln ZrO 2 catalyst has been improved and the selectivity was increased by 85% comparing with the conventional titania catalyst. With the addition of the rare earth such as lanthanum, neodymium, to zirconia as catalyst, the selectivity increased by 72% and 60% respectively in comparison with the bare titania catalyst. |
