摘　　要：对H2和含硫化合物在MoS2边缘表面的吸附活化及反应机理的理论研究结果进行了概述。重点描述了H2在MoS2表面的吸附、解离、硫覆盖度对H2吸附解离的影响以及含硫化合物在MoS2表面的吸附和反应。在原子水平上揭示了硫化钼催化剂上H2的吸附解离机理和加氢脱硫反应机理。The theoretical study results regarding adsorption and activation and reaction mechanism of H2 and sulfur compounds on MoS2 edge surface were reviewed, including detailed description on adsorption, desorption, influence of sulfur coverage on adsorption-desorption of H2 on MoS2 edge surface, and adsorption and reaction of sulfur compounds on MoS2 edge surface. The mechanism for adsorptiondesorption of H2 and mechanism for hydrodesulfurization （HI）S） reaction on MoS2 catalysts were dis- cussed from atomic level.
