The present work emphasizes on synthesis of metal incorporated mesoporous MCM-48 materials and evaluates their catalytic activity towards styrene oxidation. Ti and Cr loaded MCM-48 materials with varying Si to Ti or Cr molar ratios have been synthesized by one step hydrothermal method. The prepared catalysts were characterized using various techniques such as XRD, FT-IR, UV–Vis DRS, N₂ adsorption–desorption and SEM–EDX analysis. Catalytic activity of the synthesized materials towards the liquid phase oxidation of styrene was performed in presence of aqueous hydrogen peroxide as oxidant where benzaldehyde was obtained as major product. The effect of various reaction parameters viz. temperature, catalyst amount, styrene to H₂O₂ molar ratio etc. were studied to observe the change in styrene conversion as well as selectivity towards benzaldehyde.

本工作着重于掺入金属的中孔MCM-48材料的合成，并评估其对苯乙烯氧化的催化活性。通过一步水热法合成了具有变化的Si与Ti或Cr摩尔比的负载Ti和Cr的MCM-48材料。制备的催化剂使用XRD，FT-IR，UV-Vis DRS，N ₂吸附-解吸和SEM-EDX分析等多种技术进行表征。在存在过氧化氢水溶液作为氧化剂的情况下，合成的材料对苯乙烯的液相氧化具有催化活性，其中以苯甲醛为主要产物。各种反应参数的影响。温度，催化剂用量，苯乙烯至H ₂ O ₂ 研究了摩尔比等，以观察苯乙烯转化率的变化以及对苯甲醛的选择性。
