Abstract :
Eight kinds of simple semiconducting spinel ferrites, MeFe2O4, were prepared by self-combustion method. To determine the material characteristics were performed X-ray diffraction, SEM observations, EDAX spectroscopy and BET analysis. The ferrites have tested catalytically in combustion reaction of three diluted gases: acetone, ethanol and methanol. The results revealed a pronounced decrease in the combustion temperature when Mg-, Cu- and Ni-ferrites are used as catalysts.
