将铁镍合金引入碳载体，赋予其磁性能，进一步通过置换反应负载金属钯，制备了磁性钯碳催化剂。使用扫描电子显微镜、能谱仪、氮气吸附仪、磁学测量仪以及加氢催化实验综合考察了样品的组成、结构、磁性与催化加氢性能。结果表明，实验制得的含钯5%的磁性钯碳催化剂，钯颗粒(5~10 nm)均匀分布于材料表面，具有优异的软磁性能，饱和磁化强度较高，可与溶液快速磁分离。使用制备的磁性钯碳催化剂进行硝基苯加氢实验发现，所制备的催化剂有良好的催化活性，能快速地将硝基苯还原为苯胺。

The carbon carrier magnetic properties by introducing iron-nickel alloy into it, and magnetic palladium on carbon catalyst is prepared by further displacement reaction. Using surface area and porosity analyzer, magnetic meter, thermal gravimetric analysis, scanning electron microscopy and catalytic hydrogenation experiment, the composition, structure, magnetism and catalytic hydrogenation properties of the samples were studied. Results showed that the magnetic catalyst with 5% palladium has outstanding soft magnetic properties and can be quickly separated from the solution. The magnetic Pd/C catalyst shows fine catalytic activity in the nitrobenzene hydrogenation experiment, and the reduction of nitrobenzene to aniline can be quickly realized.
