|
Abstract:
在本文中，选用Fe(III)离子和1,1’-二茂铁二甲酸作为有机配体通过一种简单、直接的溶剂热的方法合成了具有三维花状多级结构的金属–有机框架(Fe-MOFs)微米球。结果表明合成的Fe-MOFs微米球的粒径约为5.5 μm。通过氮气吸附–脱附曲线测定Fe-MOFs微米球的比表面积为112 m2g？1。此外，在过氧化氢溶液中，所制备的Fe-MOFs微米球通过芬顿反应对亚甲基蓝显示出优异的催化降解活性。
In this work, three-dimensional flowerlike hierarchical Fe-based metal-organic frameworks (Fe-MOFs)microspheres were synthesized by a simple and direct solvothermal route by the coordi-nation between Fe(III) ions with the carboxylic ligands of 1,1’-ferrocenedicarboxylic acid. The re-sults indicated that the size of the flowerlike microspheres was about 5.5 μm. The nitrogen adsorp-tion experiment revealed that the surface area of the Fe-MOFs microspheres was about 112 m2g？1. Moreover, the obtained Fe-MOFs microspheres presented excellent catalytic activity for degradation of methylene blue (MB) in H2O2 solution via Fenton reaction.
