Synthesis and Characterization of Doped TiO2 Nanoparticles by the Sol-Gel Method and Investigation of Photocatalytic Activity

Cu2+,Ce3+-doped nanostructure TiO2 -coated Nd3+ (TiO2 /Nd3+) were prepared by sol-gel method. TiO2 were synthesized by the sol-gel method using tetra n-butyl orthotitanat (TBT) as a precursor. The prepared nanoparticles characterized by FT-IR, XRD, SEM- EDS and TEM. The XRD showed that the major phase of nanocomposite is anatase. The morphology of the TiO2/Nd3+/Cu2+and TiO2 /Nd3+/Ce3+ microsphe...

Investigation of photocatalytic degradation of phenol by Fe(III)-doped TiO2 and TiO2 nanoparticles

In this study Fe (III)-doped TiO2 nanoparticles were synthesized by sol-gel method at two atomic ratio of Fe/Ti, 0.006 and 0.034 percent. Then the photoactivity of them was investigated on degradation of phenol under UV (<380 nm) irradiation and visible light (>380 nm). Results showed that at appropriate atomic ratio of Fe to Ti (% 0.034) photoactivity of Fe(III)-doped TiO2 nanoparticles increa...

Synthesis, Characterization and Investigation of Photocatalytic Activity of transition metal-doped TiO2 Nanostructures

In this work, M-doped TiO2 nanostructures (M: Fe, Co and Ni) were synthesized by reverse microemulsion method. The as-prepared products were analyzed by different techniques such as scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). The effect of various dopants (Fe, Co and Ni) on ba...
