XPS/STM study of model bimetallic Pd-Au/HOPG catalysts

- The model Pd-Au/HOPG catalysts preparation has been studied by XPS and STM.
- Model “core-shell” type Pd-Au/HOPG catalysts with different Pd/Au ratios were prepared.
- Heating of the “core-shell” Pd-Au/HOPG samples up to 400 °C leads to alloy formation.
- Contribution of parameters controlling the properties of Pd-Au alloyed particles has been discussed.
