1.Introduction
Metal organic frameworks (MOFs) are a new class of solid
porous materials that are attracting great interest as a potential
material for gas storage and separation because of their extraordinary
surface areas,and fine tunable surface properties.1-
3 Until now,MOFs have been widely investigated for the
storage and separation of H2,CH4,CO2 and hydrocarbons.3-9
Studies to explore the use for MOFs for harmful gases (e.g.
SO2,H2S,NO) adsorption and removal are relatively sparse
compared to studies on their use for hydrogen storage and
carbon capture.10-13 In the past decades,adsorption of SO2 into
porous materials such as porous carbon,zeolites has been
proposed and investigated by different techniques in order to
develop industrial desulfurization process.14-19 Recently,Zn-
MOF-74 has been found to improve the SO2 adsorption by a
factor of 3 compared to activated carbons and be the best
performing MOF among six prototypical MOFs.20 Very recent
breakthrough measurements showed that Mg-MOF-74 provides
a better adsorption of SO2 gas than other MOF-74 series
(with Zn,Ni,Co).21 Indeed,MOF-74 [M2(dhtp),dhtp = 2,5-
dihydroxyterephthalate] compounds have hexagonal one dimensional
pores containing a high density of coordinatively
unsaturated open metal sites that can potentially interact with
guest molecules (see Figure S1 in Supporting information).
