ABSTRACT K. Y. Simon Ng This is a postdoctoral industrial fellowship awarded under the GOALI program. It is to support Dr. Haryani Permana to work in the General Motors North American Research and Development Center with Dr. David Belton. The goal of the effort is to fill a gap in the fundamental understanding of palladium-rhodium interactions in automotive emission control catalysts. The activity of a planar model catalyst is compared with the high-surface-area supported palladium-rhodium catalyst to established the relevance of the model system. The model catalyst is studied using ultrahigh-vacuum surface analysis, in-situ infrared spectroscopy, and scanning probe microscopy to gain insight on the interactions of palladium and rhodium under various conditions. This research is relevant to the design of more effective and longer lived catalytic converters for control of nitrogen oxides and hydrocarbons in automotive emissions. ***

摘要 K. Y. Simon Ng 这是 GOALI 计划下授予的博士后工业奖学金。 是为了支持Haryani Permana博士与David Belton博士一起在通用汽车北美研发中心工作。 这项工作的目标是填补对汽车排放控制催化剂中钯-铑相互作用的基本了解的空白。 将平面模型催化剂的活性与高表面积负载钯铑催化剂进行比较，以建立模型系统的相关性。 使用超高真空表面分析、原位红外光谱和扫描探针显微镜对模型催化剂进行研究，以深入了解钯和铑在各种条件下的相互作用。 这项研究与设计更有效、寿命更长的催化转化器有关，用于控制汽车排放中的氮氧化物和碳氢化合物。 ***
