The FTIR spectra of RGO GO Fe O MRose Fe

3(a) and 3(b) respectively) clearly show that Abiraterone acetate GO was reduced during the hydrothermal process, the peaks of CO stretching and OH bending vibration at 1700 and 1400 cm−1, respectively, in the FTIR of GO has been removed while the peak position of the C-O band was shifted from 1050 to 980 cm−1[21]. The peak at 580 cm−1 is assigned to the FeO bond vibration of Fe3O4[29]. In Fig.
