C. Oliva et L. Forni, EPR spectroscopy revealing the mechanism of methane flameless combustion catalyzed by La0.9M0.1CoO3 (M = Eu, Ce), APPL MAGN R, 18(4), 2000, pp. 475-481
The electron paramagnetic resonance spectra of La0.9M0.1CoO3 (M = Eu, Ce) c
an explain the lower oxygen availability observed with the Eu-, with respec
t to the Ce-doped catalyst for methane flameless combustion. With the forme
r sample, paramagnetic O- ions adsorb more easily on the internal-pore surf
aces, forming ferromagnetic spin bags.
