- •
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.
