NSF-CGP Fellowship: Reaction Kinetics and Mechanisms for the Reduction of a Copper Oxide Surface with H Atoms

9802702韦达 该奖项为印第安纳州大学博士后研究员Miles J.韦达博士与日本琦玉市鸠山日立高级研究实验室高级研究科学家Hrvoje Petek博士合作进行为期24个月的研究访问提供资金。 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，铜上的氧-氢反应，作为一个模型系统，应该提供新的见解过渡金属上的多相催化。 虽然对催化有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具有几个优点，使其成为一个基本感兴趣的系统。 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热点问题有一定的启示作用。 该项目得到了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的支持。 ***

9802702 Weida This 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. ***
