In situ encapsulation of platinum clusters within H-ZSM-5 zeolite for highly stable benzene methylation catalysis

Well-dispersed and tiny Pt clusters within hierarchical ZSM-5 are prepared via a direct hydrothermal method. The facile in situ encapsulation of Pt in zeolites endows the catalyst with excellent activity, high stability and superior recyclability for benzene methylation with methanol.
