The MS signals of NO (m/e=30) and O2 (m/e=32) as functions of desorption temperature were recorded during NO-TPD imder He flow for perovskites (Table 6). A broad NO desorption centered at 200 °C with one minor shoulder at 90 °C and another one at 388 °C was observed in the TPD of NO profdes for LaCoOs. Upon Cu substitution the low temperature peak is entirely suppressed, the 200 °C one is substantially increased and shifted to higher temperature so that it interferes with the minor high temperature one. Similar NO desorption features were found for lanthanum manganites and ferrites after NO adsorption, representing three superimposed desorption peaks. In Section 4, TPD of NO + O2 studies over...
