Flat, electrically conducting models of Mo and CoMo sulfides on SiO2 and Al2O3 have been very successful in elucidating the sulfidation chemistry of the oxidic catalyst precursors. In this paper, we show that the model approach enables industrially relevant preparation studies of alumina-supported CoMoS systems with catalytic turnover and selectivity similar to that of industrial HDS catalysts
