Comparison Nanostructure Behaviour of Copper Species on the Silicamatrix Xerogels

The incorporation of copper species is synthesized  in a silica matrix by the sol-gel method. We have doped copper ions and copper particles using two different copper sources: Cu(NO۳)۲.۳H۲O and copper particles chemically synthesized. We can prepare the particles of copper metallic, cuprous and cupric oxide and  compare the synthesis and characterization copper species on the silica matrix.  On this way, their structures  are analyzed by FT IR spectroscopy and XRD diffraction at  ۲۰۰,۴۰۰ and ۶۰۰°C temperatures. we have recognized three main region contain Rocking (R), Bending (B )and Stretching  (S)  on their structure using FT IR spectrum. Also, the SEM micrographs and chemical analysis are compared by EDX of Cu and CuO/SiO۲ together. Average size of  particles was determinated about ۱۵۰-۲۰۰ nm  for copper particles and about ۵۰ nm for copper ions by TEM micrograph.
