Structure Sensitivity in the Catalysis of Olefin Isomerizations

美国国家科学基金会化学部分析与表面化学项目将资助加州大学河滨分校Francisco Zaera教授的研究项目。Zaera博士和他的学生将在分子水平上对多相催化剂结构变化转化为催化选择性变化的因素进行理解，并提出新的合成方法，以制备明确定义的催化剂，以利用这种结构-性能相关性。为了实现这些目标，表面科学研究将在越来越复杂的系统上进行，从真空下的单晶模型系统开始，逐步纳入高气体通量和支持粒子的使用。基于胶体和自组装化学的合成方法将被开发用于生产具有明确金属颗粒尺寸和形状的负载催化剂，以优化特定烯烃异构化过程的选择性。这些研究将涉及研究生和本科生的参与。将加强与拉丁美洲研究小组的合作，并将大力鼓励来自代表性不足群体的学生参与研究。

The Analytical and Surface Chemistry Program of Chemistry Division of the National Science Foundation will support the research program of Professor Francisco Zaera at the University of California, Riverside. Dr. Zaera and his students will develop a molecular-level understanding of the factors that make changes in the structure of heterogeneous catalyst translate into changes in catalytic selectivity and to advance new synthetic methodology for the preparation of well-defined catalysts to take advantage of this structure-performance correlation. To accomplish these goals, surface-science studies will be carried out on systems of increased complexity, starting with single-crystal model systems under vacuum and evolving to incorporate the use of high gas fluxes and supported particles. Synthetic methodology based on colloidal and self-assembly chemistry will be developed for the production of supported catalysts with well-defined metal particle sizes and shapes to optimize selectivity in specific olefin isomerization processes. The studies will involve the participation of both graduate and undergraduate students. Collaborations with Latin American research groups will be forged, and student participation from underrepresented groups in research will be strongly pursued.
