氧化锆负载硒催化苯酚氧化反应

Se/ZrO_(2)-Catalyzed Oxidation of Phenol

氧化锆负载硒可以由易得的二氧化锆与硒氢化钠反应制备.研究表明,该材料可催化苯酚氧化,制备对苯醌.与传统硒催化氧化反应相比,该反应无需使用化学氧化剂,而是可以直接利用分子氧为氧化剂,从而显著降低合成成本,并且相对安全.氧化锆负载硒是一种稳定的含硒材料,可以反复多次回收利用而不会失活.其卓越的催化氧化性能有望应用于工业.

Se/ZrO_(2) can be prepared via the reaction of readily available zirconia with NaHSe.The material can catalyze the oxidation of phenol to prepare p-benzoquinone.Compared with traditional selenium-catalyzed oxidation reactions,this reaction does not require the use of chemical oxidants,but can directly utilize molecular oxygen as the oxidant,significantly reducing synthesis costs and being relatively safe.Se/ZrO_(2) is a stable selenium-containing material that can be recycled and reused for multiple times without deactivation.Its excellent catalytic oxidation performance is expected to be used in industry.
