摘要
Two series of Cu0.5Co0.5Fe2O4 ferrites were obtained by thermal or mechanochemical treatment of hydroxide carbonate precursor. The effect of the annealing temperature and the milling time, respectively, on the formation of the mixed ferrite phase was studied by DSC, XRD, Mossbauer spectroscopy and TPR with hydrogen. The catalytic behavior of the samples was tested in methanol decomposition to CO and H-2. The initial phase composition of the obtained ferrites and the formation of the catalytic active phase under the reaction medium could be controlled by the preparation procedure used.
