Effect of two isomeric benzene dicarboxylic acid ligands on the synthesis of metal organic frameworks (MOFs)

Metal–organic frameworks (MOFs) are a new class of crystalline materials consisting of metal ions linked together by organic ligands, resulting in a highly microporous network. Among all porous materials, MOFs are the best candidates for H2 – adsorption. In this work, hydrothermal condition was used for producing MIL-101. We investigated different temperature conditions and the effect of isomeric organic ligands on reaction efficiency. Cr(III) salt were combined with a benzene dicarboxylic acid ligands ({1,4- dicarboxylic acid} L1) or ({1,2-dicarboxylic acid} L2 ). The corresponding microporous network were generated by mixing the Cr(III) salt with L1. The structural order and textural properties of the synthesized materials were studied by FT-IR, XRD, and nitrogen adsorption-desorption analysis
