We doped the silica xerogels samples using two different copper sources:Cu(NO3)2·2.5H2O and copper particles chemical synthesized. The samples were studied as a function of annealingtemperature. It is found that the by heat treatment and the appropriate copper precursor we can produce particles ofmetallic Cu, cuprous and cupric oxide.
