Preparation and characterization of the nanocomposites SiO2/H-bond hydrogensulphate (hydrogenselenate).
Original language description
The nanocomposites representing interesting H-bond compounds (Na3H(SO4)(2), RbHSO4, RbHSeO4, and Rb3H(SeO4)(2)) in the silica matrix were prepared by the sol-gel method. Resulting samples were characterised by X-ray diffraction, IR spectroscopy and electron microscopy. Transition temperatures of the nanocomposites were determined using DSC and compared with the T-C of the pure bulk active compounds. The shifts of the T-C towards lower temperatures or the disappearing of the certain effects in the case nanocomposites were observed. A possible explanation of these phenomena was proposed using the analogy with the superparamagnetic compounds.
