Development of Multifunctional Nanocomposites for Tandem Reaction Catalysis

在这个项目中，将使用一种新颖的、本质上绿色的合成工艺来生产一种多功能多相纳米复合催化剂，用于两个或两个以上的串联反应。串联催化剂纳米复合材料将包括贵金属纳米颗粒和嵌入在多孔金属氧化物载体中的强酸性聚合物。所提出的用于生产纳米复合催化剂的合成工艺通过使用简单和直接的方法独立地改变三种组分来提供对催化剂活性的无与伦比的控制。贵金属纳米粒子将用于催化氢化反应，而强酸性聚合物将用于顺序催化羟烷基化反应。将被瞄准的具体应用包括异戊烯的羟烷基化反应以生产叔戊基甲醚(TAME)。

In this project, a novel, inherently green synthesis process will be used to produce a multifunctional heterogeneous nanocomposite catalyst to for use in two or more tandem reactions. The tandem catalysts nanocomposites will incorporate precious metal nanoparticles and strong acid polymers embedded in a porous metal oxide support. The synthesis process that is proposed for producing the nanocomposite catalysts provides unparalleled control over catalyst activity by using a simple and straightforward method to independently vary the three components. The precious metal nanoparticles will be used to catalyze hydrogenation while the strong acid polymers will be used to sequentially catalyze hydroxylalkylation in tandem. The specific applications that will be targeted include hydroxylalkylation of isoamylenes to produce tertiary amyl methyl ether (TAME).
