• Zeolites belong to a special class of crystalline aluminosilicates. Zeolite synthesis involves crystallization under high pH conditions from a diverse silica gel and an alumina source combined with water. The resulting nanoporous materials, called zeolites, are widely used in industrial applications as adsorbents, catalysts, and ion exchangers.
• Zeolite Socony Mobil-5 （ZSM-5） is a high-silica pentasil zeolite developed by Mobil Oil Company in 1972. H-ZSM-5 is the H form, or protonic type, of ZSM-5. In H-ZSM-5, H+ ions occupy the zeolite ion exchange sites. H-ZSM-5 can be synthesized with an infinite number of different Si/Al ratios, the variation of which affects the material's crystal configuration, porosity, and particle size, and impacts the overall strength and distribution of acid sites.
