Abstract

A noticeable improvement in the structural properties of Mn–Zn ferrite obtained by the solution combustion method was observed when the gel was additionally dried before self-combustion. The catalytic activity of thus prepared nanosized Mn–Zn ferrite has been also studied. The powders after combustion process were analyzed by X-ray diffraction and it was found that they possess pure spinel phase. The ferrite particles were agglomerated wherein powders obtained from the modified solution combustion method (gel additionally dried) characterized sponge-like structure and developed specific surface area. This ferrite material exhibits a significantly higher total acidity and it is reduced in the lower temperature. As a ferrite catalyst, prepared by the modified solution combustion method, possesses both acid and base centers, which allows to proceed the bimolecular ketonization reaction. The yield and selectivity of ketone increase with temperature with a maximum at 440 °C. Taking into account the obtained yield and selectivity results in the butan-1-ol conversion the Mn0.6Zn0.4Fe2O4 ferrite prepared in low temperature can be used as potential dehydrogenation catalyst.
