Features of the Real Structure of Metallic Silver Nanoparticles Located in Channels of Mesoporous Silicate SBA-15

Аннотация

The features of diffraction on silver nanoparticles located in channels of mesoporous silicate SBA-15 are analyzed. A computer simulation of diffraction patterns is performed for crystallites with different sizes, the cubic structure, and stacking faults. The experimental diffraction patterns are compared with simulated ones. Together with the stacking fault concentration, the average crystallite sizes are determined in the direction normal to the close packed layers and along the layers in the crystal structure.
