Abstract

Nitrogen doping of a graphite surface by ion bombardment has been found to enhance the durability of deposited Pt clusters for H₂-D₂ exchange reaction. Scanning tunneling microscopy suggests that this high durability is originated from the stabilized monolayer morphology of the Pt clusters. From the comparison with the case of argon ion bombardment, stabilized morphology has been ascribed to the nitrogen-doping effect such as an electron doping, which enhances the interface interaction between the Pt monolayer cluster and the graphite surface rather than the effect of the dangling carbon atoms at the carbon vacancy.
