Abstract

An oxygen plasma treatment was used to prepare Fe-doped TiO2 nanoparticles. The anatase and rutile phases of TiO2 nanoparticles were achieved by an atmospheric pressure chemical vapor deposition method. The nanostructures were doped by Fe atoms to obtain a ferromagnetic nanostructure based on TiO2 nanoparticles. Atomic force microscopy and magnetic force microscopy were used for morphological and magnetic investigation of as-prepared samples. Measurements have confirmed the induced magnetic moment of the structures. Magnetic field-induced wettability of the prepared nanostructures was investigated in dark and under UV and visible light. The results showed a considerable enhancement in the wettability of the structure by applying the magnetic field.
