ABSTRACT
 
Advances in the preparation and characterization of well-defined platinum nano-particles on highly oriented pyrolytic graphite (HOPG) are reviewed. Platinum particles ranging from one atom to hundreds of nanometers can be prepared by various techniques including sputtering, electrodeposition, and lithography. The scanning tunnelling microscopy (STM) and the trapping mode atomic force microscopy (TMAFM) are the most promising characterisation techniques. The dynamics of the morphology of platinum nano-particles are discussed together with molecular simulation studies. The platinum on HOPG system serves as an ideal model electrocatalyst. Some original kinetics data of methanol oxidation are reported.
