摘要

摘要通过对共沉淀前驱体进行热处理，制备了成分为Cu1−xCoxFe2O4, x= 0.2和0.8的铜钴铁氧体。通过TG-DSC、XRD、透射和转换电子Mössbauer能谱和程序升温还原氢对所得材料进行了表征。对铁氧体在甲醇分解制一氧化碳和氢气中的催化性能进行了测试。

Copper-cobalt ferrites as catalysts for methanol decomposition

AbstractCopper-cobalt ferrites with composition Cu1−xCoxFe2O4, where x= 0.2 and 0.8 were prepared by thermal treatment of co-precipitated precursor. The obtained materials were characterized by TG-DSC, XRD, Transmission and Conversion Electron Mössbauer spectroscopy and temperature programmed reduction with hydrogen. The catalytic properties of ferrites were tested in methanol decomposition to CO and hydrogen.
