Abstract—A pyrolyzate of iron phthalocyanine is studied with Mossbauer spectroscopy and transmission electron microscopy. The phase composition and magnetic state were found for pyrolysis products (α-Fe, γ-Fe, Fe3C, and magnetite). Morphological features of carbon and iron-containing phases (metal particles of various shapes and sizes, as well as carbon nanotubes, carbon hollow nanopolihedra, and nongraphitized carbon) are determined. The morphology and structure of iron phthalocyanine pyrolyzates and diphthalocyanines of rare-earth elements are comparatively analyzed.
