✦ Synopsis

Various kinds of surface area y-Mo,N were synthesized by a topotactic reaction between MOO, and NH, under relatively mild conditions. It was found that the space velocity of NH, and the particle size of MOO, were very important for the synthesis of high surface area y-Mo,N in a large batch. The percent of micropore volume in the range of 20-30 A gradually increased with increase of surface area. XRD results indicated that the intensities of diffraction peaks of high surface area y-Mo,N was different from those of low surface area. The measurements of catalytic activities for thiophene hydrodesulfuriztion and cyclohexene hydrogenation showed that high surface area y-Mo,N exhibited much higher activity than those of medium and low surface area y-Mo,N. Meanwhile, a hydrodesulfurizing mechanism of thiophene is proposed.
