An Sn‐SnOx nanoparticles were prepared by the deposition of metallic tin in the reactive atmosphere of atomic oxygen. An oxidation of Sn‐SnOx nanoparticles in the oxygen pressures up to 3 mbar at 550 K in near‐ambient pressure (NAP) cell led to the formation of SnO2 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‐SnOx round‐shaped particles with average diameter 26 nm and SnO2 nanoparticles having rutile structure and average diameter 92 nm.
