Synthesis of a MOF-derived magnetite quantum dots on surface modulated reduced graphene oxide composite for high-rate lithium-ion storage

“…The bands at 2852 cm −1 , 1097 cm −1 and 1636 cm −1 are attributed to the stretching vibrational peaks of C-H, C-O-C and CC, while the peaks at 1636 and 1386 cm −1 belong to aromatic CC bonds and C-OH bonds, respectively. 35,36 Moreover, the characteristic peak at 532 cm −1 is related to Fe-O stretching vibrations.…”
