MoS2, a 2D material, has attracted much attention after graphene. Due to its extraordinary catalytic properties, it has been widely used in in hydrotreating catalysis, electrocatalysis, photocatalysis, etc. Surface defects on 2-D MoS2 catalysts play an important role in hydrodesulfurization and hydrodenitrogenation. In this present work, a nanosized MoS2 catalyst was synthesized via hydrothermal methods with MoO3 and Na2S as precursors. A dynamic synthesis method was introduced to produce 2-D catalysts. Supercritical heptane was also introduced to the process of crystal growth in order to creates defects. The catalysts were characterized using TEM, XRD and XANES. Finally, the performance of the catalysts was evaluated using light cycled oil.
