9802702WeidaThis award provides funds to support a 24-month research visit by Dr. Miles J. Weida, postdoctoral fellow, Indiana University, for collaboration with Dr. Hrvoje Petek, Senior Research Scientist, Hitachi Advanced Research Laboratory, Hatoyama, Saitama, Japan. These collaborators will perform a detailed study of the reaction kinetics and mechanisms for the reduction of a copper oxide surface by hydrogen atoms. Copper can be viewed as a good model for more complicated transition metals. This suggests that the oxygen-hydrogen reaction on copper, as a model system, should provide new insight into heterogeneous catalysis on transition metals.Although the study of catalytically useful transition metals stems in part from their practical importance, the study of hydrogen and oxygen on copper surfaces has several advantages which make it a system of fundamental interest. One advantage is the fact that the adsorbate structures of both oxygen and hydrogen on copper have been extensively characterized. Given the level of understanding of the adsorption of oxygen and hydrogen on copper surfaces, it seems natural to extend these studies to the interaction of these species on copper surfaces. This research may shed light on such topics of current interest as self organization of adsorbates on surfaces and adsorbate-induced metal atom transport in heterogeneous catalysis. This project is supported under the Science Fellowship Program between the National Science Foundation and the Japan Foundation Center for Global Partnership.***

9802702 Weida该奖项提供资金，以支持为期24个月的研究访问博士迈尔斯J.韦达，博士后研究员，印第安纳州大学，与博士Hrvoje Petek，高级研究科学家，日立先进研究实验室，鸠山，琦玉，日本合作。 这些合作者将对氢原子还原氧化铜表面的反应动力学和机制进行详细研究。 铜可以被视为更复杂的过渡金属的良好模型。 这表明，铜表面上的氢氧反应作为一个模型体系，应该为过渡金属的多相催化提供新的见解。虽然对具有催化作用的过渡金属的研究部分源于它们的实际重要性，但对铜表面上的氢和氧的研究有几个优点，这使它成为一个基本感兴趣的体系。 一个优点是氧和氢在铜上的吸附物结构已被广泛表征。 考虑到对氧和氢在铜表面上的吸附的理解水平，将这些研究扩展到这些物种在铜表面上的相互作用似乎是很自然的。 这一研究结果可能会对诸如表面吸附物的自组织和多相催化中吸附物诱导的金属原子输运等当前感兴趣的课题有所启发。 该项目由国家科学基金会和日本基金会全球伙伴关系中心之间的科学奖学金计划提供支持。
