In this work, spinel ferrites were chosen as prototype systems for oxidative dehydrogenation of 1-butene to address the long-standing issue that whether there is a correlation between catalytic and magnetic properties of magnetic catalysts. Under zero magnetic field, the conversion was the largest for NiFe₂O₄ (74.5 mol%) and the least for ZnFe₂O₄ (12.6 mol%), with no quantative relationship between magnetism and catalytic activity. In contrast, under a magnetic field of 1603 Oe, the largest and least conversion values changed to 86.6 and 13.5 mol% for MgFe₂O₄ and ZnFe₂O₄, respectively, and these values exhibited an inverse Gauss relation with initial susceptibility.

在这项工作中，选择尖晶石铁氧体作为1-丁烯氧化脱氢的原型系统，以解决长期存在的问题，即磁性催化剂的催化性能和磁性之间是否存在相关性。在零磁场下，NiFe ₂ O ₄的转化率最大（74.5 mol％），而ZnFe ₂ O ₄的转化率最小（12.6 mol％），磁性与催化活性之间没有定量关系。相反，在1603 Oe的磁场下，MgFe ₂ O ₄和ZnFe ₂ O ₄的最大和最小转换值变为86.6和13.5 mol％，并且这些值与初始磁化率呈反高斯关系。
