The generation of catalytically relevant metal and/or metal oxide compounds supported on silica fibres is described. The systems investigated are Nio, Cuo, Cuo/ZnO, as well as perovskite-type La/Fe, La/Ni and La/Mn oxide phases. Ultrasound-aided generated vapours containing dissolved metal salt precursors are transferred onto preheated quartz fibres and transformed into the catalytically relevant phases by subsequent calcination. Analytical SEM and X-ray diffraction reveals the presence of differently crystalline, rough surfaces. The influence of the precursor salt and the conditions of calcination on the formation of the supported catalysts is discussed.
