Mo-modified MCM-48 encapsulated ZSM-5 core–shell catalyst for methane dehydro-aromatization with enhanced activity and stability

This work introduces the core–shell catalysts of Mo-modified ZSM-5 encapsulated by MCM-48. The siliceous shell protects Brønsted acid sites from exposing and reduces the loss of Mo species, enhancing the catalytic activity and durability.
