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(NO3)2.3H2O 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 200,400 and 600°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/SiO2 together. Average size of particles was determinated about 150-200 nm for copper particles and about 50 nm for copper ions by TEM micrograph.
