Synthesis,Characterization and Catalytic Isomerization Performance of Aluminosilicate Mesoporous Molecular Sieves

Aluminosilicate mesoporous molecular sieve A1-MCM-41 was synthesized under the condition of room temperature using tetraethyl orthosilicate(TEOS) as Si source,Aluminium chloride(AlCl_3)as Al source and cationic surfactant Cn TMABr as template.Many analytic methods including XRD,FT-IR,N_2-absorption-desorption were used for characterizing the structures of the synthesized A1-MCM-41 molecular sieves.The valuing results showed that the synthesized A1-MCM-41 molecular sieves had the higher catalytic performance to isomerization of endo-TCD.
