synthesis of Zn-substituted copper ferrite via nanocasting method

A series of ordered mesoporous single phase Cu1-xZnxFe2O4 spinel ferrites، with x ranging from 0. 00 to 0. 75 with a step increment of 0. 25، are prepared by a novel nanocasting route. Wide angle XRD (WXRD) results show that all the samples have a cubic structure without any impurities. Usingvinyl-functionalized mesoporous silica as a hard template plays a crucial role for transformation of precursors to the pore channels of the silica template. The physical properties of the samples are characterized by N2 adsorption-desorption، Low angle XRD (LXRD) and TEM analysis. N2 adsorption-desorption results show that all the samples have a specific surface area higher than 100 m2g-1 and pore size distribution is in the range of 6-10 nm. TEM images for x=0 and x=0. 5 confirm the preservation of mesoporous structure after removal of the template.
