Room Temperature Synthesis of N-doped Urchin-like Rutile TiO2 Nanostructure With Enhanced Photocatalytic Activity Under Sunlight
We report the synthesis of nitrogen-doped urchin-like rutile TiO2 nanostructure at room temperature without further heat treatment. The process was operated through hydrolysis of Ti(OC4H9)4 employing the direct amination of the product. The samples characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Raman spectroscopy and Brunaue...
متن کاملPhotocatalytic TiO2 Nanorod Spheres and Arrays Compatible with Flexible Applications
In the present study, titanium dioxide nanostructures were synthesized through microwave irradiation. In a typical microwave synthesis, nanorod spheres in the powder form were simultaneously produced with nanorod arrays grown on polyethylene terephthalate (PET) substrates. The syntheses were performed in water or ethanol with limited temperature at 80 ◦C and 200 ◦C. A simple and low-cost approa...
متن کاملTiO2 coated Au/Ag nanorods with enhanced photocatalytic activity under visible light irradiation.
A facile method was used to prepare uniform Au NR/TiO2 and Au/Ag NR/TiO2 core-shell composite nanoparticles. Au/Ag NR/TiO2 nanoparticles were found to display significantly enhanced visible light photo-catalytic activity compared to Au NR/TiO2 and the commercially available TiO2 nanoparticles. The enhancement mechanism was ascribed to injection of hot electrons of photo-excited Au/Ag NRs to TiO...
متن کاملPhotocatalytic discoloration of Methyl Orange on innovative parylene–TiO2 flexible thin films under simulated sunlight
Parylene films loaded with TiO2 are reported as photocatalysts in azo dye discoloration processes. The TiO2 loading of the parylene film was 0.32% (w/w) and the amount of TiO2 on the film was about two orders of magnitude below the TiO2 added in suspension to discolore the same solution of Methyl Orange used as a probe. The parylene/TiO2 films showed a similar activity in the presence of O2 or ...
متن کاملCdSe nanorod/TiO2 nanoparticle heterojunctions with enhanced solar- and visible-light photocatalytic activity
CdSe nanorods (NRs) with an average length of ≈120 nm were prepared by a solvothermal process and associated to TiO2 nanoparticles (Aeroxide® P25) by annealing at 300 °C for 1 h. The content of CdSe NRs in CdSe/TiO2 composites was varied from 0.5 to 5 wt %. The CdSe/TiO2 heterostructured materials were characterized by XRD, TEM, SEM, XPS, UV-visible spectroscopy and Raman spectroscopy. TEM imag...
