Full size image Scanning electron microscopy (SEM) revealed the curved and wrinkled nanosheet morphology of A-Fe2S1N5/SNC (Fig. 2a and Supplementary Fig. 1), which was inherited from the SNC nanosheets (Supplementary Figs. 2, 3). The thickness of the nanosheets was calculated to be 4.5 ...
The configuration of the external electron shell of the Fe atom is 3d64s2. The valence of iron is variable (divalent and trivalent iron compounds are the most stable). With oxygen, iron yields ferrous oxide, FeO; ferric oxide, Fe2O3; and ferrosoferric oxide, Fe3O4(a compound of FeO ...
