Isomorphic MOFs functionalized by free standing acylamide and organic groups serving as self supported catalysts for the CO2 cycloaddition reaction
In this work, we demonstrate the catalysis capability of a series of isomorphic MOFs functionalized on the pore walls by both acylamide and H, OH, NH2, NO2 or COOH groups in terms of the CO2 cycloaddition reaction. Without any co catalysts all of these MOF materials exhibited excellent catalysis capability but different catalytic activities depending on the organic groups decorated on the pore wall, revealing the best catalysis capability for a MOF functionalized by NH2 groups on the pore walls and a synergetic catalytic effect from both the acylamide and organic groups. Furthermore, we also estimated the recyclability of the NH2 functionalized MOF material, and found that the catalyst could be used at least four times without a significant decrease in its catalytic activity.
