Effect of the Synthesis Conditions of MIL-100(Fe) on Its Catalytic Properties and Stability under Reaction Conditions

Abstract

MIL-100(Fe) is a metal–organic framework (MOF) characterized by the presence of Lewis acid and Fe(II/III) redox sites. In this work, different synthesis methods for the preparation of MIL-100(Fe) are studied. Depending on the source of fluorine, different phases can be obtained: MIL-100(Fe) and an Fe trimesate with unknown structure which we call Fe(BTC). These materials were characterized using numerous techniques and applied in the reaction of CO2 cycloaddition with epichlorohydrin, a reaction catalyzed by Lewis acid sites. It was observed that samples with more Fe(BTC) phase were more active in the reaction. However, all samples, under reaction conditions, transformed into a less active phase.

“…Metal-organic frameworks (MOFs) were successfully studied in 1995 by Yaghi et al [1]. Due to their unique characteristics such as large specific surface area, structural flexibility, and adjustable pore size, MOFs have attracted wide attention and their applications have been expanded in many fields such as catalyst [2,3], gas storage [4], drug delivery [5], environmental treatment [6,7].…”
