Abstract

Benzene adsorption on four synthesized metal–organic frameworks (MOFs): MOF-520(Al), MOF-5(Zn), ZIF-8(ZnO–Zn), MOF-74(Mg) and three commercial MOFs: Basolite C300, Basolite F300 and Basolite Z377 at 20 °C is investigated. The materials studied feature high surface areas ranging from 950 to 3760 m2/g and large micropore volumes varying from 0.37 to 1.79 cm3/g. Nevertheless, the volume of supermicropores is one of the main factors that determines C6H6 adsorption performance of MOFs. Additionally, in the case of some MOFs, open metal sites enhance interactions between gas molecules and the surrounding framework.
