Local physico-chemical properties of nanoparticles
Abstract
The processes of interaction of gaseous reagents with coatings formed from metal nanoparticles deposited on pyrolytic graphite have been studied by scanning tunneling microscopy and spectroscopy. It is shown that the physical and chemical properties of the area of contact of nanoparticles with the substrate and the area furthest from the first one may differ. One of the reasons for the observed effects is the transfer of electric charge between the nanoparticles and the substrate.
