以30%过氧化氢水溶液为氧化剂，乙酸为溶剂，在不添加任何引发剂的条件下，在介孔Ce-MCM-41催化剂上进行环己烷液相氧化反应。该催化剂具有较高的底物转化率和较好的产物（环己醇）选择性，且可重复使用一次，活性基本不变。采用N2物理吸附、漫反射紫外-可见光谱、X射线衍射和傅立叶变换红外光谱对催化剂进行了表征。
Liquid phase oxidation of cyclohexane was carried out under mild reaction conditions over mesoporous Ce-MCM-41 catalysts using aqueous hydrogen peroxide (30%) as oxidant and acetic acid as solvent without adding any initiator. The catalysts exhibited high substrate conversion and good product (cyclohexanol) selectivity and it can be reused once with almost the same activity. The catalyst was characterized by a combination of various physicochemical techniques, such as N2physisorption, diffuse reflectance UV–vis, X-ray diffraction and FT-IR.
