In this work we have evaluated the influence of concentration and temperature of reagents on structural properties of sol-gel silica doped with copper nitrate. Samples were heated at 80 β’ C and at 120 β’ C and presented molar ratios of TEOS/Cu of 1/0.0084, 1/0.042, 1/0.084 and 1/0.0104. This last sam
