Abstract

Various CONCENTRATIONs of copper are embedded into SILICA matrix to xerogel form using copper source - Cu(NO3)2·3H2O. The xerogel samples are prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method and with determination of new molar ratio of components H2O/TEOS to be 6.2. In this investigation, the necessary amount of trihydrated copper nitrate is added to the solution in such a manner that the CONCENTRATION of the COPPER OXIDE in final solution reach to 1, 2 and 5 wt% (samples A, B and C respectively). After ambient drying, the gel samples are heated from 60 to 1000°C at a slow heating rate (50oC/h). The absorption and transmittance spectrum of various CONCENTRATIONs of copper are studied by Uv-vis spectrophotometer. THERMAL TREATMENT effects are characterized by FTIR, TGA, TEM, SEM, XRD, BET and TPR methods at different temperatures.
