项目摘要

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.

在该项目由化学部的大分子，超分子和纳米化学计划资助的项目中，史蒂文·伯纳斯克（Steven L. Bernasek）教授及其普林斯顿大学的同事将研究异质反应系统的基本机制。将使用电化学方法和光电子光谱法检查有机腐蚀抑制剂在腐蚀性流体环境中的功能。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，重点是理解手性单层和纳米图案表面的形成。基于沉积在氧化物底物上的金纳米人的有序阵列的等离子传感器将用于监测催化氧化反应的表面反应动力学。这项工作将与这些催化氧化反应的产物的内部状态分布密切相关。该项目将对研究生和本科研究学生的教育产生广泛的影响。该项目在该项目中进行的工作的跨学科性质为发展有能力的研究人员的发展提供了良好的培训理由。与工业合作者的互动使研究生面临有关商业重要性问题的问题。在这项研究中获得的基本理解将对新的腐蚀抑制剂的发展，对表面自组装的理解以及澄清异质催化氧化过程的机制产生重要影响。
