【 摘 要 】

The optimization of catalyst synthesis conditions using traditional single factor method involves extensive experimental time and costs. To overcome the drawbacks, a uniform design method was applied in the hydrothermal synthesis of nano MoS₂ catalyst. An optimal synthesis condition is reached with only a few trials. Catalyst synthesis temperature is reduced to 200 °C. The catalyst synthesized at the screened condition shows high hydrotreating activities. The results conclude that the catalyst has thread-like slabs with a lattice structure that is less mature than fully developed MoS₂. The characterization results indicate that the appearance of such structure may be due to the weak links of successive MoS₂ nuclei. The high catalytic activity is a result of the layered structure and a significantly large number of defects on the slabs.
