MoO₃ Nanobelt-Modified HMCM-49 Zeolite with Enhanced Dispersion of Mo Species and Catalytic Performance for Methane Dehydro-Aromatization.

It can be clearly observed from Figure 12 a that the methane conversion rate demonstrates an increasing trend during the initial reaction stage of less than 130 min, implying the existence of an induction period for the MDA reaction during which active site molybdenum carbide species (Mo 2 C or MoO x C y ) are generated [ 50 ].
