The interaction of propene, styrene, and phenyl-1-propene with oxygen- and Arsputtered Au(111) surfaces shall be investigated by STM and by TPR/TPD spectroscopy in order to determine adsorption sites and energies as well as reaction pathways and products. The goal of the project is two-fold: 1) The influence of lowcoordinated surface sites at steps and kinks shall be evaluated by a detailed comparison with previous TPR experiments performed by C.M. Friend et al. on relatively smooth oxygen-covered Au(111) surfaces. 2) The potential of nanoporous gold foams as catalysts for olefin epoxidation shall be marked out by using the sputtered Au surfaces as model. The project will initiate a cooperation between the groups of C.M. Friend at Harvard University and of M. Bäumer/V. Zielasek at the University of Bremen.

丙烯、苯乙烯和苯基-1-丙烯与氧和Ar溅射Au（111）表面的相互作用应通过STM和TPR/TPD光谱进行研究，以确定吸附位点和能量以及反应途径和产物。该项目的目标有两个方面：1）通过与C.M. Friend等人在相对光滑的氧覆盖的Au（111）表面上进行了研究。2)以溅射的Au表面为模型，研究了纳米多孔金泡沫作为烯烃环氧化催化剂的潜力。该项目将启动C.M.哈佛大学的朋友，M. Bäumer/V. Zielasek在不莱梅大学。
