1. A functionalized fibrous hierarchical zeolite comprising
a framework comprising aluminum atoms, silicon atoms, and oxygen atoms, the framework further comprising a plurality of micropores and a plurality of mesopores, wherein:
a plurality of nanoparticles comprising platinum are immobilized on the framework; and
a mesopore structure of the functionalized fibrous hierarchical zeolite comprises interconnected intra-crystalline mesopores;
the framework comprises a plurality of silanol groups comprising at least one of the silicon atoms and at least one of the oxygen atoms; and
at least one oxygen atom of at least one of the plurality of silanol groups is connected with the nanoparticles comprising platinum, thereby immobilizing the nanoparticles comprising platinum.
