Characterization and catalytic performance of {Mo2O2S2}-based oxothiomolybdenum cyclic clusters supported on mesoporous SBA-15

摘要

Cyclic polyoxothiomolybdate clusters containing {MO2O2S2) building unit supported on SBA-15 have been prepared by immersion SBA-15 in the corresponding cluster's solution. The measurements of low angle X-ray diffraction (LXRD), nitrogen adsorption, transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) spectroscopy indicated that the cyclic clusters were successfully loaded on SBA-15. The supported catalysts were tested in thiophene hydrodesulfurization at different temperatures, respectively. Results show that the supported catalysts have an excellent desulfurization catalytic performance for thiophene. (C) 2015 Elsevier B.V. All rights reserved.
