Study of Ag Nanocrystal distribution in Natural Clinoptilolite
The natural zeolite Ag-natural clinoptilolite supporting silver clusters is a very promising inorganic bactericide and antiviral material. The distribution of the crystals size of Ag and the variation of its mean size in natural clinoptilolite as function of the reduction temperature (tr) is reported using X - ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. The XRD and TEM studies have proved that the reduction of the Ag – natural clinoptilolite samples in H2 flow for 2.5 h at 100 ºC guarantees the formation of clusters and nanoparticles of Ag with a mean size of 4 nm, achieving in this way the largest uniformity of particle size within the group of studied samples.
