▎ 摘　　要

Composites of the Cr3+-based metal-organic framework (MIL-101) and graphene oxide (GO) have been synthesized with different ratios of MIL-101 and GO. The composites and the parent material MIL-101 were characterized 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 porosities of composites.
