Structure and Chemistry of Alloy and Oxide Films on Bimetallic Pt Surfaces

化学系的分析和表面化学（ASC）项目将支持理哈伊大学Bruce Koel教授的研究项目。Koel教授和他的学生将研究双金属Pt合金表面的结构和组成，以及氧化物-合金界面如何影响这些材料的化学和催化活性。研究小组将制备Pt和另一种金属的有序合金表面，只暴露特定的合金位点。这将简化对更复杂的现实世界表面的化学理解，并使探测具有特定组成和结构的催化位点的反应性成为可能。这项研究可能会导致开发新的和改进的催化剂。它将为催化研究领域的本科生、研究生和博士后研究人员提供极好的培训机会，这对美国经济具有重要意义。

The Analytical and Surface Chemistry (ASC) program of the Division of Chemistry will support the research program of Prof. Bruce Koel of Lehigh University. Prof. Koel and his students will study how the structure and composition of bimetallic Pt alloy surfaces, and oxide-alloy interfaces, affect the chemistry and catalytic activity of these materials. The research team will prepare surfaces of ordered alloys of Pt and another metal that expose only particular alloy sites. This will simplify understanding of the chemistry of more complicated, real-world surfaces and enable probing the reactivity of catalytic sites with a particular composition and structure. The study could lead to development of new and improved catalysts. It will provide excellent training opportunities to undergraduate students, graduate students and postdoctoral researchers in the research field of catalysis, which is of great importance to the US economy.
