engineering of supported trifunctional catalysts and their application in the representative Cu/TEMPO/NMI‐catalyzed aerobic oxidation of benzyl alcohol. The methodology allows in one single step to immobilize, with precise control of surface composition, both pyta, CuI, TEMPO, and NMI sites on azide‐functionalized silica particles. To optimize the performance of the heterogeneous trifunctional catalysts, synergistic
我们描述了一种简单且通用的方法来制备负载型三官能催化剂及其分子工程及其在代表性的Cu / TEMPO / NMI催化的苯甲醇的好氧氧化中的应用。该方法只需一步即可固定表面,即可精确控制叠氮化物官能化二氧化硅颗粒上的pyta,Cu I,TEMPO和NMI位置。为了优化多相三官能催化剂的性能,可通过调节咪唑位点的自由度以及调节相对表面组成来精细设计协同相互作用,从而使催化剂的活性明显优于相应的均相催化体系。
