HOPG corrosion accelerated by Pt particles

- an AFM study by Zyun Siroma et al
Electrochemistry Communications, Volume 7, Issue 11 , November 2005, Pages 1153-1156 (http://dx.doi.org/10.1016/j.elecom.2005.08.014)

Platinum nanoparticles were deposited on HOPG and its stability in HClO4 at a fixed potential was investigated. The formation of blisters was observed after it was kept at 1.0 V vs. RHE, especially at and around the Pt particles. FE-SEM observations revealed that Pt particles remained at their original positions after the formation of blisters.

Remarks:
AFM was done ex situ. The authors stated that systematic investigations are under way.
