A novel Cu-containing magnetic ionic liquid-based nanoporous organosilica composite with yolk-shell structure [Fe₃O₄@RF@void@PMO(IL)/Cu] was synthesized through nonsacrificial self-template strategy. The Fe₃O₄@RF@void@PMO(IL)/Cu nanosphere was characterized by using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX) and powder X-ray diffraction (PXRD) techniques. The Fe₃O₄@RF@void@PMO(IL)/Cu was used as a powerful, recoverable and reusable nanocatalyst in the Chan-Lum coupling at room temperature under aerobic conditions. The recovery test was performed to study the stability of catalytic sites under applied conditions.

通过非牺牲自模板策略合成了一种具有卵黄壳结构的新型含铜磁性离子液体基纳米多孔有机二氧化硅复合物[Fe ₃ O ₄ @ RF @ void @ PMO（IL）/ Cu]。Fe ₃ O ₄ @ RF @ void @ PMO（IL）/ Cu纳米球的特征在于使用傅立叶变换红外光谱（FT-IR），扫描电子显微镜（SEM），振动样品磁力计（VSM），透射电子显微镜（TEM） ），能量色散X射线（EDX）和粉末X射线衍射（PXRD）技术。铁₃ O ₄@ RF @ void @ PMO（IL）/ Cu在有氧条件下于室温下在Chan-Lum偶联中被用作功能强大，可回收和可重复使用的纳米催化剂。进行回收测试以研究在应用条件下催化部位的稳定性。
