Immobilization of cobalt doped rutile TiO2 on carbon nanotubes walls for efficient photodegradation of 2,4-dichlorophenol under visible light

In this work, we focused on improvement of rutile-type TiO2 degradation efficiency by cobalt doping and decorating on carbon nanotubes walls (CNTs) (Co-TiO2/CNTs). We also synthesized pure TiO2, Co-TiO2 and TiO2/CNTs samples for control experiments. The textural and morphology features of the samples were characterized by a range of analyses including: XRD, FESEM/EDX. FTIR, TEM, UV-Vis DRS and ...

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...

Antibacterial response of Cd-TiO2/PEG/folic acid nanocomposite under ultraviolet, visible light, or ultrasonic irradiation

Synthesis and characterization of Cd-TiO2/PEG/FA nanocomposite as a biomaterial is the main aim of this research. Cd-doped TiO2 nanoparticles (NPs) were synthesized by solvothermal assisted sol-gel method. Then, polyethylene glycol (PEG) was added to the as-synthesized NPs in order to modify their surface and to prevent agglomeration. In the next step, folic acid (FA) was conjugated to Cd-TiO2/...

Standalone anion- and co-doped titanium dioxide nanotubes for photocatalytic and photoelectrochemical solar-to-fuel conversion.

Several strategies are currently being investigated for conversion of incident sunlight into renewable sources of energy, and photocatalytic or photoelectrochemical production of solar fuels can provide an important alternative. Titanium dioxide (TiO2) has been heavily investigated as a material of choice due to its excellent optoelectronic properties and stability, and anion-doping proposed as...
