Figure 2. (A) Powder X-ray diffraction (PXRD) experimental patterns of MIL-101(Cr) and its hybrids containing different wt.% of GO, compared with the MIL-101(Cr) simulated pattern; (B) FTIR spectra of MIL-101(Cr) and its GO-based hybrids; (C) Derivatives of the thermogravimetry (DTG) curves for pure MIL-101(Cr) and its hybrids with varying GO contents, measured under an argon atmosphere.
