主 题：Stable MO2N Nanobelts High Catalytic Activity Ammonia Decomposition
摘 要：In the present work,high quality γ-Mo2N catalysts for ammonia decomposition were successfully synthesized via temperature programmed nitridation of α-MoO3 *** optimal conditions for the synthesis of MoO3 precursors were obtained by using the orthogonal experimental *** MoO3 precursors and the corresponding fresh and used Mo2N catalysts were characterized by various characterization techniques,including transmission electron microscopy,X-ray diffraction and N2 ***,temperature-programmed desorption by N2 or NH3 and X-ray photoelectron spectroscopy analysis were performed to better understand the chemical properties of Mo2N *** results revealed that Mo2N catalyst has good NH3 adsorption ability and facilitates the dissociation adsorption of ***,the morphology and structure of Mo2N catalysts well maintained after the ***,among the three transition metal nitrides(Mo2N,W2N and VN)and some Mo-based catalysts previously reported,Mo2N catalysts showed very high activity and *** 94% con version of NH3 could be reached at 550 ℃ with the gas hourly space velocity of 22 000 cm^3-gcat^-1·h^-1 and no obvious deactivation was observed during a 72 h test.
