通过双氧水催化分解反应动力学研究，显示磁化合成铁氧体具有较高的催化速率.利用高分辨分析电镜和电子能量损失谱测试了其显微形貌、化学组成和微区晶体结构，探讨了催化作用机理.

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.
