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.

美国国家科学基金会化学部的分析和表面化学计划将支持滨江加州大学的弗朗西斯科扎埃拉教授的研究计划。 Zaera博士和他的学生将从分子水平上理解使多相催化剂结构变化转化为催化选择性变化的因素，并推进新的合成方法，以利用这种结构-性能相关性制备定义明确的催化剂。 为了实现这些目标，将对复杂性增加的系统进行表面科学研究，从真空下的单晶模型系统开始，并逐步发展到使用高气体通量和支持粒子。 将开发基于胶体和自组装化学的合成方法，用于生产具有明确定义的金属颗粒尺寸和形状的负载型催化剂，以优化特定烯烃异构化工艺的选择性。 这些研究将涉及研究生和本科生的参与。 将与拉丁美洲研究团体建立合作关系，并将大力推动代表性不足群体的学生参与研究。
