Description
Summary:[Display omitted] MoS2 is known as core material for the hydroconversion of heavy oil in petroleum refinery due to its superior coke suppression and desulfurization activities. With the recent interest in applying MoS2 to slurry-bed reactors, it has become important to design appropriate Mo-precursors and to identify factors for evaluating them. In this review, various methods for the synthesis of MoS2 from Mo-precursors and their physicochemical properties were examined. It was revealed that several properties of Mo-precursors (dispersibility and thermal properties) and MoS2 (sulfidation degree, particle size, and stacking) serve as crucial factors in determining catalytic performance. For better catalyst design, the decomposition pathway of Mo-precursors and the effect of carbonaceous material on MoS2 were also discussed.
