Nanostructures loaded on halloysite nanotubes (HNTs) have attracted global interest, because the nanotubular HNTs could extend the range of their potential applications. In this study, we fabricated a novel nanocomposite with hollow iron nanoparticles loaded on the surface of HNTs. The structure of the iron nanoparticles can be adjusted by ageing time. Owing to the increased remnant magnetization and coercivity values, the nanocomposites loaded with hollow iron nanoparticles showed better electromagnetic performance than that with solid iron nanoparticles. This study opens a new pathway to fabricate halloysite nanotubular nanocomposites that may gain applications in the catalytic degradation of organic pollutants and electromagnetic wave absorption.
负载于埃洛石纳米管（HNTs）上的纳米结构已引起全球关注，因为管状的HNTs可扩展其潜在应用范围。在本研究中，我们制备了一种新型纳米复合材料，其为负载于HNTs表面的空心铁纳米颗粒。铁纳米颗粒的结构可通过老化时间进行调控。由于剩余磁化强度和矫顽力值的增加，负载空心铁纳米颗粒的纳米复合材料表现出比负载实心铁纳米颗粒的纳米复合材料更好的电磁性能。本研究为制备埃洛石纳米管纳米复合材料开辟了一条新途径，该复合材料可能在有机污染物的催化降解和电磁波吸收方面获得应用。
