The Analytical and Surface Chemistry (ASC) program of the Division of Chemistry will support the research program of Prof. Shouzhong Zou of Miami University Ohio. The study of Prof. Zou will focus on improving fuel cell technology. Prof. Zou and his students will use a new approach to fabricate model nanoparticle catalysts and study their electrocatalytic activities toward dioxygen (O2) reduction, as well as methanol and carbon monoxide (CO) oxidation, reactions that are of importance to the direct methanol fuel cell. The new fabrication method will result in well organized uniform nanoparticle arrays, and their size, composition, as well as interparticle distance will be well controlled. This could potentially improve the electrocatalytic activity and overall performance of fuel cells. The study will provide excellent training opportunities to undergraduate students, graduate students and postdoctoral researchers in a cutting edge interdisciplinary research field, which is of great importance to the US economy.

化学部的分析和表面化学（ASC）计划将支持俄亥俄州迈阿密大学邹守忠教授的研究计划。 邹教授的研究将集中在改进燃料电池技术上。邹教授和他的学生将使用一种新的方法来制造模型纳米颗粒催化剂，并研究它们对氧气（O2）还原以及甲醇和一氧化碳（CO）氧化的电催化活性，这些反应对直接甲醇燃料电池非常重要。 新的制造方法将导致组织良好的均匀纳米颗粒阵列，并且它们的尺寸，成分以及颗粒间的距离将得到很好的控制。这可以潜在地提高燃料电池的电催化活性和整体性能。该研究将为本科生，研究生和博士后研究人员提供良好的培训机会，在尖端的跨学科研究领域，这对美国经济非常重要。
