Abstract

The structural features of a nanocomposite FeNi3/C synthesized from a solution FeCl3·6H2O/NiCl2·6H2O/polyacrylonitrile (PAN)/dimethyl formamide (DMF) with CFe=CNi=5; 10; 20; 25 mas. % under an IR heating are studied by a combination scattering (CS), a scanning electron microscopy (SEM), and an X−ray phase analyses (XPA). It is determined that as the IR heating temperature grows from 500 to 700 °С, the FeNi3 nanoparticle size increases from about 15 to 60 nm; amorphous, microcrystalline, and nanocrystalline graphite−like carbon phases (the halo in the XPA spectrum at 2θ ≈ 8÷32°) that are characterized by more intensive band D (ν =1340÷1358 cm−1) than the band G (ν =1560÷1596 cm−1) in the CS spectrum are formed; from the data of a SEM and a CS (the G peak, ν =1596 см−1), the possibility of the graphene structure generation is suggested at 600 and 700 °С; the peak in the area of 1120 cm−1 and the high intensity of the CS spectrum in the region of 1430—1480 cm−1 reveal the formation of polymer−destruction intermediate products at the interface of nanoparticles FeNi.
