Structure and Dynamics of Heterogeneous Reactions

在这个由化学学部大分子、超分子和纳米化学项目资助的项目中，普林斯顿大学的Steven L. Bernasek教授和他的同事将研究非均相反应系统的基本机制。有机缓蚀剂在腐蚀性流体环境中的作用将采用电化学方法和光电子能谱进行研究。将使用扫描探针显微镜研究自组装有机单层表面的结构和反应性，重点是了解手性单层和纳米图案表面的形成。基于有序金纳米点阵列的等离子体传感器将被用于监测催化氧化反应的表面动力学。这项工作将与这些催化氧化反应产物的内部状态分布的测量密切相关。本项目将对研究生和本科生的教育产生广泛的影响。本项目所开展工作的跨学科性质为培养有能力的研究人员提供了良好的培训场所。与工业合作者的互动使研究学生接触到具有商业重要性的问题。在这项研究中获得的基本认识将对新的缓蚀剂的开发、对表面自组装的理解以及对非均相催化氧化过程机理的澄清产生重要影响。

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Professor Steven L. Bernasek and his coworkers at Princeton University will investigate the fundamental mechanisms of heterogeneous reaction systems. The function of organic corrosion inhibitors in corrosive fluid environments will be examined using electrochemical methods and photoelectron spectroscopy. The structure and reactivity of self-assembled organic monolayer surfaces will be studied using scanning probe microscopy, with a focus on understanding the formation of chiral monolayers and nanopatterned surfaces. Plasmonic sensors based on ordered arrays of gold nanodots deposited on oxide substrates will be used to monitor surface reaction dynamics of catalytic oxidation reactions. This work will be carried out in close connection to measurements of the internal state distributions of the products of these catalytic oxidation reactions. This project will have broad impact on the education of graduate and undergraduate research students. The interdisciplinary nature of the work carried out in this project provides an excellent training ground for the development of capable researchers. Interactions with industrial collaborators expose research students to questions of commercial importance. The fundamental understanding obtained in this research will have important impact in the development of new corrosion inhibitors, in the understanding of self-assembly at surfaces, and in the clarification of the mechanisms of heterogeneous catalytic oxidation processes.
