Abstract: The ferrite catalyst synthesized under magnetic field has a crystalline structure of spinel type FexO,with 0.75≤x≤0.85.The magnetic field can impel more Fe2+ to occupy the octahedral site,so Fe/O atom ratio, the residual magnetron and the crystal defects are increased.As a result,the spinel ferrite catalyst can increase the catalytic redox reaction rate such as decomposition of H2O2.
