摘要：
The stability of the oxidation state of antimony ion in Sn-Sb-O catalysts under the influence of operating conditions was investigated by Mossbauer spectroscopy. It was shown that the presence of the tin dioxide matrix facilitates the oxidation of the antimony ion; at the same time, the Sb5+ ions in the SnO2 rutile matrix show much higher stability under slightly reducing conditions provided by the catalytic test of propylene oxidation.
