Metal organic frameworks (MOFs) have gained a significant amount of interest for applications such as gas storage, catalysis, and gas filtration. UiO�66 zirconium�MOFs are attractive as they have been reported to have high surface areas and are chemically and thermally stable. We have synthesized several UiO�66 analogs using different functionalized organic linkers, i.e. 2�bromoterepthalic acid, 1,4�naphthalenedicarboxylic acid, 2�nitroterepthalic acid, and 2�aminoterepthalic acid, in systematic ratios to study the impact of these linkers toward adsorption for toxic chemical gases, i.e. NH3, SO2, H2S, ClCN, and CH3Br. By varying the functionalities incorporated within the MOF structure, multiple gases were found to adsorb within a single MOF. These materials were characterized using XRD, ATR�FTIR, TGA, nitrogen adsorption isotherms, water vapor isotherms, and breakthrough testing. Findings of this work will be insightful toward adsorption capacities of various chemical gases and may be applied for use in toxic gas filtration.
