Fig. 2. Exhibits the HR-TEM of nano Fe-CNB, (A) depicts the high-resolution TEM images showing clusters of carbon layer with embedded nanoparticles, (B) exhibits the thickness of the graphitic carbon sheet of 7–8 nm. (C) and (D) shows graphitic carbon having randomly scattered Fe-CNB magnetic core (highlighted using yellow dashed lines) of size 5–10 nm at different magnifications. (E) Lattice fringes of magnetic core (highlighted using yellow dotted line) with d spacing of 0.25 nm embedded in the layered graphitic carbon (highlighted using blue dotted line). (F) depicts the SAED pattern of Fe-CNB.
