Syntheses, Characterizations and Adsorption Properties of MIL-lOl/Graphene Oxide Composites

Composites of the Cr3＋-based metal-organic framework （MIL-101） and graphene oxide （GO） have been syn- thesized with different ratios of MIL-101 and GO. The composites and the parent material MIL-101 were charac- terized by X-ray diffraction, scanning electron microscopy and nitrogen adsorption. The...

Summary:Composites of the Cr3＋-based metal-organic framework （MIL-101） and graphene oxide （GO） have been syn- thesized with different ratios of MIL-101 and GO. The composites and the parent material MIL-101 were charac- terized by X-ray diffraction, scanning electron microscopy and nitrogen adsorption. The results indicated that the incorporation of large amounts of GO （10 and 20 wt%） almost did not prevent the formation of MIL-101 units, but had an obvious impact on the size of MIL-101 crystals. On the contrary, small amounts of GO added （2 and 5 wt%） prevented significantly the proper assembly of MIL-101 units, thus resulting in a pronounced decrease in the poros- ities of composites.
