Insights into the state of the MoS_2 surface and hds mechanism in CoMo Catalysts

摘要

The synergy between sulfided cobalt and molybdenum in hydrogenation and hydrodesulfurization remains intriguing in spite of the impressive amount of work it has triggered.There is no doubt that the simultaneous presence of both elements during reduction-sulfidation creates special structures and special textural properties.There is indeed a synergy for more efficient activation.But many obscure aspects remain concerning the cooperation between these elements in the catalysis of hvdrogenation(HYP)and hvdrodesulfurization {more precisely the hydrogenolysis of C-S bonds,noted C-SHG).
