Nanometer Sized Silver Particles Embedded Silica Particles—Spray Method
Spherical shaped, nanometer to micro meter sized silica particles were prepared in a homogeneous nature by spray technique. Silver nanoparticles were produced over the surface of the silica grains in a harmonized manner. The size of silver and silica particles was effectively controlled by the precursors and catalysts. The electrostatic repulsion among the silica spheres and the electro static ...
متن کاملStudy on Characteristics of Nanometer-sized Silver Iodobromide Emulsion
Ever since C.R.Berry found quantum size effect on nanometer-sized AgX grain and made studies on its anomalous absorption behaviour, much effort has been made on different aspects of nanometer-sized grain emulsion. H.Thiry, M.Iwasaki and his coworkers prepared nanometer-sized AgBr or AgBrI grain emulsion below 30nm scale and made some attempts on spectral sensitization; Investigated the mixture ...
متن کاملSurface Structure of Nanometer-Sized Zinc Ferrite Particles by the Anomalous X-ray Scattering (AXS) Method
The atomic structure of nanometer-sized zinc ferrite particles has been studied with the anomalous x-ray scattering (AXS) method as well as the ordinary x-ray diffraction. The analysis of the peak broadening indicated that little microstrain exists in these nanometer-sized particles, and the average size of the particles is estimated to be 4 nm. Since the ratio of atoms located on the surface i...
متن کاملSynthesis and characterization of Silver-Silica heterogeneous nanocomposite particles by Lithium Aluminum Hydroxide reducing method
We have used Lithium Aluminum Hydroxide reducing method of silver nitrate to prepare heterogeneous silver-silica nanocomposite particles with thiol and amino groups serving to bind the Ag nanoparticles to the surfaces of the SiO2 nanoparticles. We examined products of these reductions using FTIR, SEM, XRD and UV-vis. spectroscopy. The SiO2 nanoparticles had diameters rangi...
متن کاملSynthesis of sub-nanometer gold particles on modified silica.
The deposition of gold on silica tends to give large particles when using conventional techniques. We report the preparation of 0.8 ± 0.2 nm particles on a modified SBA-15 support. The method involves the functionalization of silica with amine groups and deposition of gold at basic pH. These catalysts are highly active and selective in the dehydrogenation of formic acid.
