Abstract
Samples of the composition CeCuO1.5/C (C = Sibunite, C-Al2O3, Taunite, oxidized Taunite) were prepared by incipient wetness impregnation in order to develop new catalysts based on supported bimetallic oxide nanoparticles for oxidative transformations of sulphur compounds. Using FTIR spectroscopy and thermal analysis in combination with mass spectrometry, the effect of the nature of the support and its oxidative treatment on the functional composition of the support surface and its thermal stability was studied. Among the supports studied, the sample on Taunite proved to be the most stable to decomposition. The thermal stability of Taunite decreases after oxidative treatment and the introduction of metal precursor salts.
