An MAS NMR study on the Mo-modified phosphoric rare earth (HZRP-1) penta-sil zeolite catalyst

An attempt was made to characterize in-situ an Mo modified phosphoric rare earth-containing penta-sil zeolite catalyst using high-resolution solid-state MAS NMR, equipped with a newly designed device for conducting catalytic reactions. It shows good activity for methane dehydro-aromatization in the absence of oxygen.
