Реферат:
Two new technical developments have been applied in order to investigate surface mobility in real time on the microscopic scale. The PEEM-technique (Photoemission Electron Microscopy) registers the local work function as induced by adsorption structures during catalytic reactions. The FEM-technique (Field Electron Microscopy) was also applied in situ during surface reactions. Both techniques are operated at low gas pressures, low emission currents and high detector amplification. Thus, gas phase ionization is omitted and still bright emission pattern are obtained.
Systems with bistable adsorption structures as well as those with oscillating reactions have been investigated. On Pt- and Pd-single crystal planes as well as on Pt-field emitter surfaces fundamental processes such as phase nucleation, reaction wave propagation and synchronization in surface reactions, could be studied during oscillatory behaviour of carbon monoxide oxidation. In a new attempt of spillover research the mobility and transfer of adsorbed particles across different surface structures (including subsurface oxides) has been investigated.
