Figure 4. (A and B) A series of XPS spectra of C1s and Fe2p core levels of the C24H24FeNP-GO sheets as a function of reaction time; (C) The Fe/C ratios obtained from the XPS spectra of GO nanosheets reacted with C24H24FeNP (red open circle) and AFc molecules (blue open circle) as a function of reaction time; (D) Magnetization curves of C24H24FeNP-GO sheets (reaction time: 96 h), GO sheets, and solid C24H24FeNP molecular powder at 2 K; (E)
