以NiCo纳米二十面体为原料，采用元素光刻法合成了从二十面体到空心球的NiCo@Pt纳米合金。采用扫描电子显微镜、透射电子显微镜、X射线衍射分析、能量色散X射线分析、X射线光电子能谱、振动样品磁力测量和紫外可见光谱等方法研究了纳米ZnO的形态、结构、磁性及其协同光催化作用。所制备的NiCo@Pt磁性空心纳米球对ZnO具有紫外光和可见光协同降解染料废水的作用。特别是在紫外光和紫外光过滤的可见光照射下，可以观察到不同的共沉淀反应，其中紫外光下的Ni 45 Co 37@Pt 18和可见光下的Ni 31 Co 26@Pt 43分别表现出最强的ZnO光催化活性增强。磁化强度Hc和饱和磁化强度Ms先随温度的升高而降低。
The NiCo@Pt nanoallys from icosahedrons to hollow spheres are synthesized through the element lithographic process based on NiCo nanoicosahedrons. The morphology, structure, magnetic property, and its synergistic photocatalysis of nano-ZnO have been investigated by scan electron microscopy, transmission electron microscopy, X-ray diffraction analysis, energy dispersive X-ray analysis, X-ray photoelectron spectroscopy, vibration sample magnetometry measurement, and UV–vis spectroscopy. The as-prepared NiCo@Pt magnetic hollow nanospheres have the UV- and visible-light-driven synergistic photocatalysis for ZnO toward the degradation of dye wastewater. Especially the different coorporation photocatalysis can be observed under UV- and UV-filtered visible-light illumination, in which Ni45Co37@Pt18 under UV-light and Ni31Co26@Pt43 under visible-light exhibit the strongest enhancement for the photocatalytic reactivity of ZnO, respectively. The coercivity Hc and saturation magnetization Ms first decrease with the ...
