Abstract: In order to develop new catalysts based on supported bimetallic oxide nanoparticles for oxidative transformations of sulfur compounds, a series of samples of the composition M1M2Ox/C (M1M2 = Ce, Mo, Cu, C= Sibunit, C@Al2O3, Taunit, oxidized Taunit) was prepared by incipient wetness impregnation. The effect of the nature of the metal precursor, support and the oxidative treatment of the support on the functional composition of the support surface and its thermal stability has been studied by means of FTIR spectroscopy and thermal analysis combined with mass spectrometry. Among the studied supports, the sample on Taunit was the most resistant to decomposition. The stability of the carbon nanotubes (CNT) Taunit support against thermal decomposition increases in the following series of samples: CuMo/Taunit <CeMo/Taunit <CeCu/Taunit <Taunit. The optimal precursors of bimetal oxides for the synthesis of a promising nanosized catalyst M1M2Ox/Taunit have been selected.
