摘要

MoS₂ was dispersed into the porosity of MCM-41 and SBA-15 ordered mesoporous materials by means of thermal spreading of MoO₃ oxide, followed by sulfidation. Catalysts with various Mo loadings were prepared (namely 9, 14 and 20 wt%), thoroughly characterized using XRD N₂-sorption, and TEM, and their activity in hydrodesulfurization of dibenzothiophene was investigated. Depending on the pore size of the support, a nanocasting of the sulfide particles was observed, and its effect on HDS activity was discussed.
