Templating route for synthesizing mesoporous zeolites with improved catalytic properties

SummaryZeolites with intracrystal mesopores have been paid much attention recently due to the combination of the advantages of mesoporous materials and zeolite crystals. This review describes the synthetic routes for preparation of mesoporous zeolites by various templates including nanostructured carbons, mesoscale cationic polymers, mesoscale organosilanes, and nanosized inorganic materials. The interaction between these mesoscale templates with silica or aluminosilicate species in the starting gels has been discussed. Furthermore, the excellent catalytic properties over these mesoporous zeolites are systemically summarized.
