A method of the hydrothermal synthesis of Fe3+-doped titanate nanotubes (TNT) is reported
in which the ultra-small Fe3O4 nanoparticles are used as the sources of Fe3+ ions. The
magnetic nanoparticles with a diameter of about 2 nm are added during the washing stage
of the hydrothermal procedure. During washing, they gradually degrade and at the same
time, the titanate product is transformed into nanotubes. The obtained nanotubes were
characterized by structural and magnetic measurements. It was found that, depending on the …

The magnetic nanoparticles with a diameter of about 2 nm are added during the washing stage of the hydrothermal procedure. During washing, they gradually degrade and at the same time, the titanate product is transformed into nanotubes. The obtained nanotubes were characterized by structural and magnetic measurements. It was found that, depending on the value of the external magnetic field, they may show the property of room temperature ferromagnetism, paramagnetism or they may be diamagnetic. It was also shown that the modified TNTs have greater photocatalytic activity compared to unmodified TNTs.
