Nitrogen and Hydrogen Gas Adsorption Properties of Microporous Ruthenium Coordination Polymers

Abstract

We investigated nitrogen and hydrogen gas adsorption properties of microporous ruthenium coordination polymers constructed from Ru II/III 2 paddle wheel motif and dicarboxylic organic linkers such as terepthalic acid, fumaric acid, muconic acid and succinic acid. In nitrogen gas adsorption measurements, we calculated adsorption parameters such as surface area (Langmuir ), pore volume and pore diameter. The relation between adsorption parameters and maximum amount of hydrogen uptake was discussed.Key words: Microporous coordination polymer, Gas adsorption, mix-valence Ru complexes IntroductionMicroporous metal coordination polymers called metal organic frameworks (MOFs) have attracted a great deal of attention in the past decade because of their captivating structural diversities and intriguing potential applications, such as gas storage, separation, catalysis, and chemical sensing. The properties of gas-adsorption into MOFs were first found in the [Cu 2 (TP) 2 ] n (TP=
