| Abstract: | Statistical adsorption and TPD studies of PO
2=1.33 and 90,440 Pa and Tads=163–523 K have revealed that Ru oxidation at high pressures begins already at Tads=300 K, while at low ones it starts at 353 K. Temperature increase leads to its surface oxidation at low pressures (1.33 Pa) and to the deep oxidation with the formation of stoichiometric oxides at high pressures (90,4440 Pa).
