Języki publikacji
Abstrakty
In this paper, we proposed a new synthesis method of a CuO-SnO2 composite based on the sol-gel technique and tin(IV) acetate as the precursor. In addition, for the first time we used a combination of high-energy homogenization and spray drying. The aim of the study was to obtain a nano-composite with a high Cu content. The system properties were investigated using XRD, TGA, TEM and SEM-EDS techniques. The obtained composite material contains an amorphous gel of tin(IV) hydroxide and crystalline copper(II) acetate. The presented method of synthesis allows for obtaining nano-composite particle sizes less than 50 nm, and a CuO-SnO2 nano-composite fraction with a particle size less than 5 nm. The small size of particles should result in high activity of the system.
W niniejszej pracy proponujemy nową metodę otrzymywania układu CuO-SnO2, wykorzystującą technikę zol-żel i octan cyny(IV) jako prekursor SnO2. Ponadto, po raz pierwszy zastosowano połączenie techniki wysokoenergetycznej homogenizacji i suszenia rozpyłowego. Celem pracy było otrzymanie układu nanokompozytowego o wysokiej zawartości Cu. Otrzymane układy zostały poddane charakterystyce za pomocą technik XRD, TGA, TEM oraz SEM-EDS. Kompozyty zawierają amorficzny żel wodorotlenku cyny(IV) oraz krystaliczny octan cyny(II). Dzięki zastosowaniu wspomnianych technik udało się otrzymać cząsteczki o rozmiarach poniżej 50 nm, jak również pewną frakcję nanokompozytu CuO-SnO2 o rozmiarach poniżej 5 nm. Małe rozmiary cząstek powinny wpływać na wysoką aktywność takiego układu.
