1. A catalyst system comprising:
a core comprising a ZSM-5 zeolite; and
a shell comprising a mesoporous fibrous silica comprising KCC-1, the shell in direct contact with at least a majority of an outer surface of the core; and
wherein:
the catalyst system has a Si/Al molar ratio of from 20 to 40, the ZSM-5 zeolite has a Si/Al molar ratio of from 20 to 60,
at least a portion of the shell has a thickness of from 50 nanometers (nm) to 600 nm, and
the shell further comprises metallic nanoparticles comprising cobalt, as well as heteroatoms chosen from one or more of aluminum, boron, gallium, titanium, zirconium, and hafnium.
