Magnetically Decorated Halloysite Nanotubes: The Halloysite Mass Content Assessment in Nanocomposite

Halloysite nanotubes (HNTs) were uniformly decorated with magnetite nanoparticles through co-precipitation approach. The resulting magnetic nanocomposite was assessed by several characterizations. The synthesis of Fe۳O۴ nanoparticles was confirmed by X-ray diffraction (XRD) pattern and the field emission scanning electron microscope (FESEM) images revealed that the spherical Fe۳O۴ nanoparticles were successfully anchored on the HNTs. The HNTs mass content was calculated in the obtained nanocomposite, and compared to the initial feed ratio by the aid of thermogravimetric analysis (TGA). The results suggest that this synthesis approach will result in a reliable magnetic HNTs with the same HNT content as the feed ratio.
