Nanocomposites of the type 30 % CuFe2O4/70 % SiO2 were synthesized using the modified sol–gel method starting from tetraethylorthosilicate, metal nitrates (Fe(NO3)3·9H2O, Cu(NO3)2·3H2O) and the diol: 1,3-propane diol. The obtained hybrid gel, which contains within the pores, the metal nitrates and diol, was thermally treated at 140 °C, when the redox reaction between metal nitrates and 1,3-propane...
