Abstract

Abstract

In this study, a new type of bola surfactant was synthesized and used as the template to prepare ZSM-5 molecular sieve (H-ZSM-5) with nano lamellar structure. The ethyl orthosilicate and sodium metaaluminate were used as silicon source and aluminum source, respectively. The H-ZSM-5 was prepared by hydrothermal method, and the mole ratio was 30 NaOH∶2.5 NaAlO₂∶120 SiO₂∶5 SDA∶4800 H₂O. The prepared ZSM-5 molecular sieves were characterized by scanning electron microscopy, transmission electron microscopy, X-ray and nitrogen adsorption, thermogravimetric analysis, etc. The static adsorption experiments of formaldehyde on the traditional ZSM-5 and H-ZSM-5 were carried out. It was found that the adsorption capacity of H-ZSM-5 molecular sieve was significantly higher than that of the traditional microporous ZSM-5. The evaluation of adsorption performance by using toluene vapor molecule with larger molecular diameter showed that the nano-sheet H-ZSM-5 zeolite had the ability to adsorb VOCs molecules with larger molecular structure and the applying potential in indoor air purification.
