Facile Synthesis and Spectroscopic Studies of SiO2-Core/ZnS-Shell Nanostructure
SiO2/ZnS core/shell nanostructures have been synthesized at room temperature by a simple wet chemical method. The prepared materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR), UV–vis spectroscopic and transmission electron microscopy (TEM) studies. X-ray diffraction pattern exhibits peaks correspond to the cubic phase of ZnS. Th...

TiO2-SiO2 photocatalytic nanostructure film on windshield for self-cleaning purposes was prepared via sol–gel dip-coating method. TiO2 films were prepared on automotive glass pre-coated with a SiO2 layer by a dip-coating method followed by annealing at 500 °C for 30min. The films were characterized using X-ray diffraction XRD and scanning electron microscopy SEM, FE-SEM techniques. The TiO2-SiO...
متن کاملQuantum size effect and catalytic activity of nanosized single-crystalline spherical β-Ga2O3 particles by thermal annealing of liquid metal nanoparticles
We report on the synthesis of nanosized single-crystalline spherical b-Ga2O3 particles (GONP) by thermal annealing of gallium nanoparticles (GaNP), which previously has been prepared under ultrasonication. GONP displayed a spherical morphology and the particle size reflected that of GaNP. The nanoparticles have been confirmed as crystalline b-Ga2O3 by powder X-ray diffraction. The selected area...
