Abstract

The existing theories regarding the promotion effect of Co(Ni)-Mo/MoS2 catalysts have been critically analyzed on the basis of literature data, and the model of the Co-Mo-S phase has been discussed. It has been concluded that the structure which causes the promotion of the hydrogenation and hydrodesulfurization activities of MoS2 is based on the formation of an Ni(Co)-Mo bond, which results in the appearance of at least a binuclear cluster stabilized on the MoS2 surface.
