Original Paper


A facile and convenient approach was proposed to highly fill carbon nanotubes with various nanoparticles, such as Fe3O4 and CoO. Furthermore, in the case of Fe3O4 and CoO nanoparticles, the effect of reaction conditions on the filling quality and confinement of CNTs on the size and morphology of NPs were explored. The encapsulation procedure in our work can provide a valuable guidance for filling a variety of NPs into hollow structure apart from CNTs. In addition, as a proof-of-concept demonstration, the magnetic properties of Fe3O4 in the absence and presence of CNTs were measured to indicate that magnetization and the blocking temperature of superparamagnetic Fe3O4 can be adjusted, which is due to the confinement effect of CNTs.
