Guidelines

Cílem navrhované práce je výzkum elektronové struktury a reaktivity modelových katalyzátorů založených na oxidech ceru. V rámci tohoto tématu se budou studovat ultratenké vrstvy kysličníku ceritého a jejich reakce s kovovou podložkou a adsorbovanými plyny metodou rentgenové fotoelektronové spektroskopie (XPS = ESCA) a komplementarními technikami. Experimenty budou probíhat na kombinované aparatuře pro scanovací tunelovou mikroskopii (STM), difrakci pomalých elektronů (LEED), termodesorpční spektroskopii (TDS) a XPS.

Preliminary scope of work

Preliminary scope of work in English

The suggested work is aimed at investigations of the electronic structure and reactivity of model catalysts based on cerium oxides. In frame of this topic interactions of ultra thin layers of ceria with metal support and adsorbed gases will be studied by means of X-ray Photoelectron Spectroscopy (XPS = ESCA) and complementary spectroscopic techniques. The experiments will take place on a combined apparatus for Scanning Tunnelling Microscopy (STM), Low Energy Electron Diffraction (LEED), Thermo Desorption Spectroscopy (TDS) and XPS.
