摘　　要：以ＬａＴｉＯ２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９０％的良好结果，讨论了溶剂、反应温度、反应时间、过氧化氢浓度、催化剂用量。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.
