摘要
With O_2 and CO as the molecular probes,the reactivity of oxygen species of perovskite-like oxides SmMnO_3 and SmFeO_3 was studied by thermodesorption spectroscopy(TDS)and temperature- programmed reaction spectroscopy(TPRS)in an ultrahigh vacuum system.The results of the experiment implied that the oxidation of CO on SmMO_3 may follow Langmuir-Hinshelwood mechanism.
