Metal organic frameworks constructed from organic bridging ligands and inorganic connecting nodes have been widely accepted as new materials for various applications. Recently, various MOFs with various structural properties have been studied as catalysts for CO2 fixation reaction due to its high CO2 adsorption capacity and ability to concurrently occupy Lewis/Bronsted acidic and basic sites. The 100% atom-economic reaction of epoxides with CO2 yielding cyclic carbonates is a well-known and established procedure that avoids the use of common toxic raw materials. In this work, we examined the catalytic activity of an aluminium based microporous MOF, Al(OH)(ndc). The structure of Al-MOF consists of aluminium coordination octahedra which bridged by ndc (2, 6-naphthalene dicarboxylic acid) linkers. Al(OH)(ndc) was synthesized by solvothermal method and characterized by using SEM, XRD, TGA, FT-IR, BET surface area etc. The catalytic activity of the MOF for the cycloaddition reaction of CO2 and epoxide were carried out in the presence of co-catalyst by using propylene oxide (PO) as the epoxide. The role of temperature, pressure, time and the amount of loaded catalyst were also studied. |
