TiO2-coated nanostructures for dye photo-degradation in water

The photocatalytic efficiency of a thin-film TiO2-coated nanostructured template is studied by dye degradation in water. The nanostructured template was synthesized by metal-assisted wet etching of Si and used as substrate for the deposition of a thin film of TiO2 (10 nm thick) by atomic layer deposition. A complete structural characterization was made by scanning and transmission electron micr...

Ag–TiO2 doped photo catalytic degradation of Procion blue H-B dye in textile washwater

The photocatalytic degradation of Procion blue H-B dye in biodegraded textile washwater has been investigated for the complete removal of color and maximum reduction of chemical oxygen demand (COD). Pseudomonas putida was utilized for obtaining biodegraded textile washwater. In this process, silver-doped TiO2 photocatalyst was prepared and experiments were carried out to study the effects of UV...

Nitrogen doped TiO2 for efficient visible light photocatalytic dye degradation

In this study, Nitrogen doped TiO2 photocatalysts were prepared by the sol gel method and physicochemical properties were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), photoluminescence, and energy dispersive X-ray spectroscopy (DRS) techniques. The XRD data indicated that the nanoparticles had the same crystals structures as the pure TiO2</su...

A New Step-based Photoreactor for Degradation of Acid Dye using N-TiO2-P25-coated Ceramic Foam under Visible Light

In the present study, a new step-based photoreactor was presented to investigate the degradation of Acid Red 73 under visible light irradiation. Four N-TiO2-coated alumina foams prepared by the modified sol-gel process were arranged in each step as photocatalyst. The experimental design methodology was employed to assess the interaction between the operational parameters in the step-...
