摘要：

A variety of metal-organic frameworks (MOFs) have been reported as efficient catalysts for CO2 fixation reactions, such as cycloaddition to cyclic carbonates. The permanent porosity of the frameworks and the Lewis acidity of the MOF metal sites have been considered as the major contributors to the catalytic activity in the cycloaddition of CO2. In this study, we have, instead, focused on the effects of the organic functional groups for effective catalytic ability. A total of eight different functionalized Zr-based MOFs were tested. It was revealed that the non-functionalized pristine UiO-66 MOF (UiO = University of Oslo) showed the best conversion at low temperature (77% at 50 degrees C), whereas the hydroxy-functionalized UiO-66-OH MOF displayed the best conversion at high temperature (91% at 140 degrees C). The Zr-MOF could be recycled up to four times without a significant decrease in the reactivity. (C) 2018 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
