Abstract The present paper reports a Density Functional Theory (DFT) study of a Mo12S24 cluster as a model of the active phase in hydrodesulphurisation (HDS). Different types of sulphur vacancies are considered and compared. The interaction of a thiophene molecule with a double vacancy is simulated leading to the determination of a stable configuration which corresponds to a flat adsorption on the edge of the MoS2 sheets. The dissociative adsorption of molecular hydrogen on a double vacancy is also considered.
