Ag-doped TiO2 Nanocomposite Prepared by Sol Gel Method: Photocatalytic Bactericidal Under Visible Light and Characterization

In  this  reaserch,  photocatalyst  titanium  dioxide  was  doped  with silver  and modified  by  polyethylene  glycol  by  sol  gel method  and the  samples  were  characterized  by  X-ray  diffraction  (XRD)  and scanning  electron  microscopy  (SEM).  The  purpose  of  the  present study  was  to  evaluate  the  photocatalytic  bactericidal  effects  of prepared nanocomposite on human p...

Characterization and photocatalytic activity of SiO2-TiO2 mixed oxide nanoparticles prepared by sol-gel method

SiO2-TiO2 mixed oxides have been prepared by sol-gel technique from titanium tetraisopropoxide and tetraethylorthosilicate. The prepared materials were characterized by X-ray diffraction, FT-IR spectroscopy, scanning electron microscopy, nitrogen physisorption and UV-vis diffuse reflectance spectroscopy. The results indicate that compared to pure TiO2, the SiO2-TiO2 mixed oxides show higher the...

Synthesis of TiO2-CuO mesoporous composite nanoparticles by sol-gel method and evaluation of structural, optical and photocatalytic properties

Given the growing importance of photocatalysts in the industrial wastewater treatment, in this study, TiO2-CuO (TC) composite nanoparticles were synthesized by sol-gel method. Tetrabutyl orthotitanate (TBT), copper nitrate-3hydrate and ethanol were used as titanium dioxide precursor, copper oxide precursor and solvent, respectively. The structural, optical, photocatalytic activity and BET-BJH...

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...
