摘　　要：以ＬｎＺｒＯ２作为苯酚选择氧化催化剂，用过氧化氢氧化，得到邻苯二酚选择性高达８５７％的良好结果，添加稀土元素镧、钕的氧化锆催化剂与单纯的二氧化钛催化剂相比，邻苯二酚选择性分别提高了７３５％和６７８％。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.
