尖晶石铁氧体催化还原CO_2的研究进展

Progress on the Catalytic Reduction of Carbon Dioxide by Spinel Ferrites

尖晶石型铁氧体是一类性能优良的磁性材料,其在实际中被广泛用作为微波吸收剂、磁记录材料和其它功能材料;同时在催化、电子信息和生物技术等领域具有良好的应用前景.由于温室效应日益严重,如何使温室效应的主要成分CO2气体固定化已成为当今世界各国研究关注的主要课题.本文重点概述了尖晶石型铁氧体(MFe2O4)的制备方法以及催化CO2还原为C和CH4的研究进展.

As a kind of excellent magnetic materials, spinel ferrite can be used as microwave absorber, magnetic recording materials and other functional materials in practical application. Meanwhile, it has also good application prospect in catalyst, electronic information and biology technology fields, etc. Due to the greenhouse effect increasingly serious, how to immobilize CO2 gas which is a major components of the greenhouse effect, has become a focus. The research progress is expounded emphatically for preparation methods of spinel ferrite （MFe2O4） and its catalytic reduction CO2 into C and CH4.
