Fabrication and Characterization of Rutile TiO2 Nanocrystals by Water Soluble Precursor
In this research, TiO2 nanoparticles were synthesized by a simple wet chemical method. TiCl4 was used as precursor in hydrogen peroxideand ethanol. The TiO2 nanoparticles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), electron dispersive spectroscopy (EDS) and UV-Vis spectrophotome...

متن کاملMeasurement of Local Atomic Displacements Reveals Interaction of Au Nanocrystals with Rutile (TiO2) Surface Steps
Advances in atomic resolution electron imaging now promise a detailed understanding of nanostructures and their interfaces, as well as defects. A major challenge in nanostructure characterization is the study of 3D interfaces that deviate significantly from a flat, 2D, interface. Here, we report a significant progress in the study of 3D interfaces by examining local displacements of Au atoms ne...
متن کاملBand alignment of rutile and anatase TiO2
The most widely used oxide for photocatalytic applications owing to its low cost and high activity is TiO2. The discovery of the photolysis of water on the surface of TiO2 in 19721 launched four decades of intensive research into the underlying chemical and physical processes involved2–5. Despite much collected evidence, a thoroughly convincing explanation of why mixed-phase samples of anatase ...
