This project, supported in the Analytical and Surface Chemistry Program of the Chemistry Division, is directed toward achieving a fundamental understanding of catalytic reactions at solid surfaces. Solid state Nuclear Magnetic Resonance (NMR) spectroscopy used in situ is the principal instrumentation involved. Among the catalytic materials to be investigated are zeolites, metal halides and metal oxides. Theoretical modeling via computer will provide guidance and confirmation in the interpretation of experimental NMR results. Transient approaches will be used to determine the identity and structure of short-lived reaction intermediates. In addition, photodissociation processes in confining media are to be studied. This research will increase our understanding of how chemical reactions promoted by catalysts take place. Catalytic materials play a very important role in the production of chemical products in such technologically significant areas as the petroleum, lubricants, and pharmaceutical industries. Catalysts are used for many reasons and significant among them are energy efficiency and a more positive environmental impact. The type of spectroscopy (NMR) employed in this work is well suited to study the way catalytic reactions occur at solid materials such as zeolites and metal oxides.

该项目由化学部的分析和表面化学项目支持，旨在对固体表面的催化反应有一个基本的了解。在现场使用的固态核磁共振（NMR）光谱是主要的仪器。研究的催化材料包括沸石、金属卤化物和金属氧化物。通过计算机进行理论建模将为实验核磁共振结果的解释提供指导和确认。瞬态方法将用于确定短寿命反应中间体的特性和结构。此外，还研究了密闭介质中的光解过程。这项研究将增加我们对催化剂促进的化学反应如何发生的理解。催化材料在石油、润滑油和制药等技术重要领域的化学产品生产中起着非常重要的作用。催化剂的使用有很多原因，其中重要的是能源效率和更积极的环境影响。在这项工作中使用的光谱（NMR）类型非常适合研究催化反应在固体材料（如沸石和金属氧化物）上发生的方式。
