Characterization, photocatalytic, and antibacterial activity of Ag–TiO2 nanoparticles prepared by electrical arc discharge method
A simple, inexpensive and one-step synthesis route of Ag-TiO2 nanoparticles by arc discharge method isreported. The resulting nanoparticles were characterized using X-ray diffraction and scanning electronmicroscopy. X-ray diffraction patterns demonstrate dominance of rutile to anatase phase in TiO2 andformation of silver metal on TiO2 after arc discharge process. Scanning electron microscopy im...
متن کاملSynthesis of TiO2 nanoparticles in pure 2-hydroxyethylammonium formate room temperature ionic liquid and investigation of its photocatalytic properties
TiO2 nanoparticles were synthesized by modified sol—gel method using pure room temperature ionic liquid(RTIL) 2-hydroxyethylammonium formate as a reaction medium. The structure and morphology of TiO2nanoparticles were characterized with X-ray powder diffraction (XRD), BET surface analysis and scanningelectron microscopy (SEM). TiO2 nanoparticles were synthesized in open and closed vessels. The ...
متن کاملSynthesis, characterization and photocatalytic activity of Fe2O3-TiO2 nanoparticles and nanocomposites
In this pepper Fe2O3 nanoparticles were synthesized via a fast microwave method. Then Fe2O3-TiO2 nanocomposites were synthesized by a sonochemical-assisted method. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy and Fourier transform infrared spectroscopy. The photocatalytic behaviour of Fe2O3-TiO2 nanocomposites was evaluated using the degrad...
متن کاملSynthesis 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...
متن کاملSynthesis and Characterization of Anatase-coated Multiwall Carbon Nanotube for Improvement of Photocatalytic Activity
Sol-gel technique was used to coat multiwall carbon nanotubes (MWCNTs) with anatase titania to increasing the surface area and improve the photocatalytic activity of TiO2. Room temperature ballistic conduct of MWCNT combined with semiconducting behavior of anatase brought about a photocatalytic improvement of ~37 % with respect to the highest methyl orange decolorization flair. For characteriza...
