Abstract:
The first observation of 109Ag NMR spectra from Ag metal particles dispersed on alumina and silica, in some cases at Ag contents as low as 0.1 wt.% is reported. The Knight shifts and relaxation times are found to be typical for Ag bulk metal. The distortions of the Ag metal crystal lattice were found to contribute to 109Ag NMR line width. The estimation of Ag crystal size at which the metal-to-nonmetal transformation takes place was made from studies of samples with different size distribution of supported Ag particles.
