The deposition of gold on the atomically smooth surface of HOPG results in the formation of 3D gold particles with the BE(Au 4f7/2) = 84.0 eV. The form of gold deposited on the surface activated with argon ions (HOPGA) depends on coverage Θ(Au). At low coverages, the deposition leads to the formation of isolated gold atoms. The atoms are stabilized on the graphite surface by chemical bonding with carbon with the formation of surface compounds Au-Cn. The 3D gold particles are resistant to oxidation with nitrogen dioxide at a pressure 3·10-5 torr. The isolated atoms of gold under these conditions are oxidized to form the state Au(III) stabilized on the surface of graphite. The stabilized gold atoms may act as active sites of gold catalysts
