英文摘要: Temperatured-programmed reduction (TPR) of hydrogen was used to investigate the reducibility of Mo species on Mo/HZSM-5 catalysts prepared by different methods, and the possible six H-2-consumption peaks were assigned precisely with the help of H-1 MAS NMR. The TPR peaks corresponding to the reduction of Mo species associated with Bronsted acid sites were first identified. In addition, the catalytic performance of various Mo-based catalysts was studied for methane dehydroaromatization. The Mo species that is located in the channels of HZSM-5 zeolite and associated with Bronsted acid site is more active and stable for the formation of one-ring aromatics in the methane dehydroaromatization.
