Термическая деструкция полидиметилсилоксана на кремнеземе, модифицированном Fe2O3

The process of thermal degradation of polydimethylsiloxane on the surface of fumed silica and Fe2O3/SiO2 nanocomposites was studied using temperature-programmed desorption mass spectrometry. It was established that the presence of Fe2O3 nanoparticles reduce the temperature of methane formation. The beginning of СН4 formation is observed at 150-200 °C, whereas in the case of the fumed silica - above 300 °C. The influence of water on the process of high-temperature hydrolysis of Si-C bonds was considered.
