项目摘要

In this project funded by the Chemical Structure, Dynamics and Mechanisms Program of the Division of Chemistry, Andrew J. Gellman (Carnegie Mellon University), E. Charles H. Sykes (Tufts University) and David S. Sholl (Georgia Institute of Technology) will collaborate to develop and apply methods for high throughput study of structure sensitive surface chemistry. The core of the experimental program is the preparation, characterization and study of curved single crystal metal surfaces that expose continuous distributions of surface orientations; i.e. regions of the surface that expose different step and kink densities. Spatially resolved experimental tools such as STM, XPS, and LEIS will be used to characterize the local structures of these surfaces and to measure surface reaction kinetics at each point. This effort will resolve the role of step and kink density in several surface reactions. Complementary computational modeling tools will be used to understand the role of surface orientation in surface reaction kinetics. These methods will greatly accelerate the study of structure sensitive surface chemistry. The impact of this work will be development of a fundamental understanding of several catalytically important surface reactions. The broader impact will include outreach to high school students, exposure of undergraduates to research and the development of short videos on surface science and nanoscience for public viewing.

在这个由化学系化学结构、动力学和机理计划资助的项目中，Carnegie Mellon大学的Andrew J.Gellman、塔夫茨大学的E.Charles H.Sykes和佐治亚理工学院的David S.Sholl将合作开发和应用高通量结构敏感表面化学研究的方法。该实验计划的核心是弯曲单晶金属表面的制备、表征和研究，这些表面暴露出表面取向的连续分布，即暴露出不同台阶和扭结密度的表面区域。空间分辨实验工具，如STM、XPS和LEIS将被用来表征这些表面的局部结构并测量每个点的表面反应动力学。这一努力将解决台阶密度和扭结密度在几个表面反应中的作用。将使用互补的计算建模工具来了解表面取向在表面反应动力学中的作用。这些方法将极大地促进结构敏感表面化学的研究。这项工作的影响将是对几个具有催化作用的重要表面反应有一个基本的了解。更广泛的影响将包括面向高中生的外联，让本科生接触研究，以及开发关于表面科学和纳米科学的短片供公众观看。
