摘要: 以空心玻璃微球作为模板材料，采用化学镀法在模板表面沉积了均匀的非晶态Ni-P合金镀层，用化学溶解法去除内部的空心玻璃微球模板，制备出非晶态Ni-P合金空心微球。分别利用EDS、SEM、XRD等手段对制品进行表征，以硝基苯液相加氢为探针反应，考察了非晶态Ni-P合金空心微球的催化加氢性能。结果表明，非晶态Ni-P合金空心微球具有良好的催化活性和循环使用性能。

Abstract: Amorphous Ni-P alloy hollow microspheres were prepared by a template method in which hollow glass microspheres were used as templates. Ni-P coatings were deposited onto the templates by electroless plating and the templates were removed by chemical dissolving method. The products were characterized by EDS, XRD and SEM. The hydrogenation catalytic properties of the prepared amorphous Ni-P alloy hollow microspheres were investigated by using reaction of nitrobenzene hydrogenation in liquid phase. The results show that the amorphous Ni-P alloy hollow microspheres exhibit super hydrogenation catalytic properties and circle performance.
Key words: template method; hollow microsphere; electroless plating; amorphous Ni-P alloy; hydrogenation catalytic property
