Interaction of propene, styrene, and phenyl-1-propene with oxygen-sputtered gold surfaces

丙烯、苯乙烯和苯基-1-丙烯与氧和砷溅射金（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。该项目的目标是双重的：1)通过与C.M. Friend等人在相对光滑的氧覆盖的Au（111）表面上进行的TPR实验的详细比较，应评估台阶和扭结处低协调表面位点的影响。2)以溅射金表面为模型，标记出纳米多孔泡沫金作为烯烃环氧化催化剂的潜力。该项目将启动哈佛大学C.M. Friend小组和Bäumer/V. M.小组之间的合作。Zielasek在不来梅大学说。

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.
