Within this project a new method for the preparation of supported intermetallic nanoparticles will be developed. The as designed procedure will allow the synthesis of a broad range of intermetallic nanoparticles applicable in heterogeneous catalysis. While other conventional procedures need individual development for each system, the vapour solid method may become a procedure which is generally applicable by only changing the physical parameters dependent on the vapour pressures of the reactants. As the derived method will need a combination of metals with vapour pressures differing in several orders of magnitude, the following materials are thought to be of interest: Non-volatiles: Palladium, Ruthenium, Rhodium, Iridium, Gold, Nickel, Cobalt, Iron Volatiles: Zinc, Tellurium, Selenium, Antimony, Phosphorus Powder support materials: alumina, silica, titanium dioxide, carbon The starting materials are often commercially available, still also in house preparation of supported metallic nanoparticles will be done for a more precise control of educts. In a first attempt alumina supported Pd Zn, Pd Te, Ni Zn, Ni P and Ni Te will be synthesised. The prepared catalysts will be characterized chemically and physically by total reflection X ray fluorescence spectroscopy, atomic absorption spectroscopy, powder X-ray diffraction, gas adsorption, scanning electron microscopy, energy dispersive X¬-ray spectroscopy, (high resolution) transmission electron microscopy. Investigation of the materials regarding composition and structure will be key to evolve the method for the preparation of promising catalyst materials.
