U.S.-France Cooperative Research: Studies of Model C-H Bond and Si-H Bond Activation Processes on the Surfaces of Large[RG]n and [CH4]n Clusters

这项为期三年的美法实验物理化学合作奖涉及犹他大学和法国萨克莱原子能中心的研究人员和学生。主要研究人员，美国的William H. Breckenridge和法国的Benoit Soep和Jean-Michel Mestdagh领导了这次合作。他们将研究激发原子和表面产生的金属氧化物的反应，以激活碳氢键。C-H键的活化在许多技术过程中都很重要，比如碳氢化合物裂解、天然气合成、氢化和有机合成。这些过程中的许多要么在化学上极其复杂，要么在难以表征和识别导致断键的过程的条件下发生。实验结果的合作和比较将阐明键断裂过程，并了解C-H活化如何在这些技术体系中发生。实验将在犹他大学和法国萨克雷进行。法国小组将进行光敏C-H键活化“表面”模型实验。犹他大学的金属氧化物/甲烷实验对这些进行了补充。实验结果的合作和比较将阐明键断裂过程，并促进对这些技术体系中碳氢活化如何发生的理解。研究生将受益于高级培训和参与由国际团队进行的合作实验。该奖项代表了美国方面对NSF和CNRS的平行提案。美国国家科学基金会将支付美国研究员及其学生的旅费和生活费。法国研究中心将支持法国研究人员和学生访问美国。

0124920BreckenridgeThis three-year award for US-France collaboration in experimental physical chemistry involves researchers and students at the University of Utah and the Center for Atomic Energy (CEN) in Saclay, France. The principal investigators, William H. Breckenridge in the US, and Benoit Soep and Jean-Michel Mestdagh in France, lead this collaboration. They will study reactions of excited atoms and metal oxides produced at the surface in order to activate C-H (carbon-hydrogen) bonds. Activation of C-H bonds is important in a wide variety of technological processes such as hydrocarbon cracking, synthesis of chemicals from natural gas, hydrogenation, and organic synthesis. Many of these processes are either extremely complex chemically or occur under conditions which make it difficult to characterize and identify the processes responsible for bond breaking. The collaboration and comparison of experimental results will elucidate the bond-breaking process and understanding of how C-H activation occurs in these technological systems. Experiments will be performed at the University of Utah and in Saclay, France. The French group will conduct photosensitized C-H bond activation "surface" model experiments. These are complemented by metal oxide/methane experiments at the University of Utah. The collaboration and comparison of experimental results will elucidate the bond-breaking process and advance understanding of how C-H activation occurs in these technological systems. Graduate students will benefit through advanced training and participation in the collaborative experiments performed by an international team. This award represents the US side of parallel proposals to the NSF and the CNRS. NSF will cover travel funds and living expenses for the US investigator and his students. The CNRS will support visits by French researchers and students to the United States.
