An Sn‐SnO x nanoparticles were prepared by the deposition of metallic tin in the reactive atmosphere of atomic oxygen. An oxidation of Sn‐SnO x nanoparticles in the oxygen pressures up to 3 mbar at 550 K in near‐ambient pressure (NAP) cell led to the formation of SnO 2 nanoparticles. Both kinds of nanoparticles were investigated by means of photoelectron spectroscopies (XPS, NAP‐XPS), energy‐dispersive X‐ray spectroscopy (EDX), reflection high‐energy electron diffraction (RHEED) and scanning electron microscopy (SEM). Characterization of nanoparticles revealed Sn‐SnO x round‐shaped particles with average diameter 26 nm and SnO 2 nanoparticles having rutile structure and average diameter 92 nm.
