Abstract

Molybdenum supported on zeolite HZSM-5 (Mo/HZSM-5) is an effective bi-functional catalyst for methane dehydroaromatization (MDA) that allows direct conversion of methane into aromatics. In this work, Wang et al. determine the forms, locations, and deactivation sequence of the active sites in Mo/HZSM-5 and prepare more stable MDA catalysts accordingly.
