Chemistry, Physics and Technology of Surface| Summary: | Using molecular layering method and impregnation of silica Asil-300 with copper acetylacetonate, Cu(acac)2, nanocomposites of CuO/SiO2 have been synthesized containing CuO nanoparticles with crystallite size of 36–88 nm and concentration of 1.6–7.4 wt. %. The thermal transformations of surface structures of Cu(acac)2 have been studied by infrared spectroscopy and differential thermogravimetry. Heating the adsorbed Cu(acac)2 and chemisorbed –Cu(acac)-groups up to 550 °C leads to the formation of tenorite – monoclinic copper oxide on silica surface. |
