This study proposes a novel strategy for preparing Ti-Beta zeolite with nanosized crystals and incredibly stable isolated Ti4+ ions under solvent-free conditions via intensified interzeolite transformation from a commercially available Ti-MWW source. The obtained Ti-Beta exhibited unique catalytic performance in the oxidation of cyclohexene with aqueous hydrogen peroxide.
本研究提出了一种在无溶剂条件下,通过商业可得的 Ti-MWW 沸石源的强化同晶转化,制备具有纳米级晶体和极其稳定的孤立 Ti4+离子的 Ti-Beta 沸石的新策略。所得到的 Ti-Beta 在环己烯与过氧化氢水溶液的氧化反应中表现出独特的催化性能。
