The thesis presented here had the goal to gain a better understanding concerning the stability and catalytic activity of supported Au nanoparticles by utilizing well-defined Au/TiO2(110) model catalysts. Therefore new preparation methods for Au/TiO2(110) samples had to be found, the thermochemical stability of differently sized and shaped Au particles was examined and the catalytic activity of those model catalysts was studied. For the latter item, it was also an important task to develop new reactors to overcome the general problem that, due to the small active surface of those samples, only very small product concentrations are present in the reaction gas.
