Ev. Kondratenko et al., OXIDATIVE COUPLING OF METHANE OVER OXIDES OF ALKALI-EARTH METALS USING N2O AS OXIDANT, Catalysis today, 24(3), 1995, pp. 273-275
Using a CH4-O-2 and a CH4-N2O reaction mixture, N2O was shown to be a
more active and a more selective oxidant then O-2 when CH4 conversion
was similar for both oxidants. It was established that the defect stru
cture of SrO was changed under catalytic conditions. The participation
of defects of SrO in the N2O decomposition was proposed. The presence
of hydrogen significantly enhances the decomposition of N2O and the f
ormation of C2H6 over SrO.
