英文摘要: The surface properties and hydrogenation/dehydrogenation performance of Mo2N/gamma -Al2O3 were studied. It was showed that the supported molybdenum nitride was highly dispersed, and that the surface species of passivated molybdenum nitride was molybdenum oxynitride or molybdenum nitride modified by oxygen, which was very different from fresh molybdenum nitride. The molybdenum nitride was not active for C6H6 hydrogenation, but highly active for dehydrogenation of cyclohexene/cyclohexane and cracking of cyclohexane. The passivated molybdenum nitride was active for C6H6 hydrogenation and more active for C6H6 cracking than molybdenum nitride and H-2-reduced molybdenum oxide. All results showed that the hydrogenation/dehydrogenation sites are Mo and the cracking sites are related to N atom. The catalytic performance of Ni(Co)Mo/gamma -Al2O3 for cracking of benzene and cyclohexane were also studied.
