Two novel hierarchical porous IM-5-S and IM-5-M materials were synthesized using mesoporous silica SBA-15 and MCM-48 as the silica sources, and for comparison conventional IM-5-C zeolite was also synthesized with the same synthesis composition. IM-5-S and IM-5-M samples exhibited larger crystal sizes and different textural properties than the conventional IM-5-C zeolite. Moreover, Mo-modified catalysts,...
A Mo-modified catalyst, Mo-IM-5, was prepared for the non-oxidative aromatization of methane, and for comparison, Mo-ZSM-5 was also synthesized for the same reaction. The physical properties and acidities of the samples were characterized by XRD, SEM, BET and IR spectroscopy. Compared with Mo-ZSM-5, the Mo-IM-5 catalyst showed both a higher methane conversion and higher benzene selectivity. In addition,...
