Zeolites are crystalline microporous solids whose frameworks are composed of corner-sharing tetrahedral TO4 units (T=Si,Al, P, etc.), forming periodic one-dimensional (1D) to threedimensional (3D) channels with an aperture size of typically<2 nm. Because of their unique pore structures, large specific surface area, strong acid sites, high thermal/hydrothermal stability and molecular-level shape selectivity, zeolites are widely used as catalysts, adsorbents and ion exchangers in the fields of oil refining, petrochemical industry, coal chemical industry and daily chemical industry.
