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

该奖项将支持明尼苏达大学的Lanny D. Schmidt教授与墨西哥国立自治大学（UNAM）的Miguel Jose Yacaman教授在墨西哥墨西哥城的一项研究合作。研究人员打算在更正式的基础上建立一个正在进行的多相催化项目。特别是，他们计划制备催化剂，表征其在不同气氛下的反应性，并确定微观结构如何影响反应性。重点将放在NO+CO反应中的Rh-Ce催化剂颗粒和烃氢解和异构化中的Pt-Sn颗粒上。这些系统分别被用作汽车污染催化剂和石油精炼催化剂，因此对美国和墨西哥都非常重要。该奖项将有助于促进两所院校之间的学生、高级人员、催化剂样品和TEM显微图的交流。明尼苏达大学的小组主要对结构和反应性的关系感兴趣，而UNAM小组将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.
