    Notes: Abstract The behavior of lattice oxygen species of the ferroelectric material during methane oxidation was investigated using a nonthermal plasma reactor packed with BaTiO 3 pellets. Lattice oxygen species in BaTiO 3 play an important role in the formation of N 2 O and the oxidation of CH 4 . The oxidation products such as CO and CO 2 were formed from independent reaction pathways. Lattice oxygen species were able to preferentially oxidize the carbon species deposited on the pellet surface into CO. Also, N 2 O and NO x were independently formed in the N 2–O 2 reaction, suggesting that different oxygen species give N 2 O and NO x. N 2 O was produced by the oxidation of molecular nitrogen with lattice oxygen species.

    Effect of conversion of NO2 into no on the catalytic reduction of NO2 with C3H6 in excess O2 (1998)
    Springer
    Reaction kinetics and catalysis letters 63 (1998), S. 53-59

    ISSN: 1588-2837
    Keywords: NO2 reduction by propylene ; gold ; rhodium ; platinum ; alumina

    Notes: Abstract During the reduction of NO2 by C3H6 in O2 over alumina-supported Au, Rh and Pt it was found that three parallel reactions take place,i.e., reduction of NO2 to N2 and N2O, partial decomposition of NO2 to NO and oxidation of C3H6 to CO and CO2. In the absence of C3H6, the NO2→NO+O2 reaction reaches a fast equilibrium on Rh and Pt but not on Au and γ-Al2O3. Addition of C3H6 to the NO2+O2 mixture leads to the formation of NO above equilibrium conversion levels.
