摘要

采用自燃法制备了8种简单的半导体尖晶石铁氧体MeFe2O4。通过x射线衍射、SEM观察、EDAX光谱和BET分析来确定材料的特征。对铁氧体在丙酮、乙醇和甲醇三种稀释气体的燃烧反应中进行了催化试验。结果表明，以镁铁、铜铁和镍铁为催化剂时，燃烧温度明显降低。

Semiconducting spinel ferrite powders prepared by self-combustion method for catalyst applications

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.
