U.S.-Mexico Collaborative Research: Electron Microscopy of Catalyst Particles

该奖项将支持教授兰尼D。施密特 明尼苏达大学与 国立大学的Miguel Jose Yacaman教授 墨西哥自治市（Autonoma de Mexico，UNAM），位于墨西哥城。 的 研究人员打算建立一个更正式的基础上， 正在进行的多相催化研究项目。 特别是， 他们计划制备催化剂，表征它们的反应性 在不同的大气中， 结构影响反应性。 请注意， NO+CO反应中的Rh-Ce催化剂颗粒和Pt-Sn 颗粒在烃氢解和异构化中的作用。 这些系统用作汽车污染催化剂， 石油精炼催化剂，因此， 对美国和墨西哥都很重要 该奖项将有助于促进学生的交流， 高级人员、催化剂样品和TEM显微照片 两个机构之间。 该小组在大学的 明尼苏达州主要关注的是 结构和反应性，而UNAM集团将作出贡献 他们在微观结构表征方面的专业知识。

This award will support Professor Lanny D. Schmidt of the University of Minnesota in a research collaboration with Professor Miguel Jose Yacaman of the Universidad Nacional Autonoma de Mexico (UNAM) in Mexico City, Mexico. The researchers intend to establish on a more formal basis an ongoing program on heterogeneous catalysis. In particular, they plan to prepare catalysts, characterize their reactivity in different atmospheres, and determine how micro- structure affects reactivity. Attention will be directed at Rh-Ce catalyst particles in the NO+CO reaction and Pt-Sn particles in hydrocarbon hydrogenolysis and isomerization. These systems are used as automotive pollution catalysts and petroleum refining catalysts, respectively and are therefore of great importance to both the U.S. and Mexico. This award will help to promote the exchange of students, senior personnel, catalyst samples, and TEM micrographics between both institutions. The group at the University of Minnesota has been primarily interested in the relation of structure and reactivity while the UNAM group will contribute their expertise in micro-structure characterization.
