Abstract:
A method is described for preparing isolated Fe nanoparticles on the surface of poly(tetrafluoroethylene) (PTFE) nanogranules. The composition and atomic structure of the nanoparticles are investigated by transmission electron microscopy and EXAFS, x-ray emission, and Mössbauer spectroscopic techniques. The nanoparticles have a complex composition and structure and contain α-Fe (15%). The majority phase in the nanoparticles is iron carbide (48%). On the surface of the PTFE nanogranules, the nanoparticles react with fluorine, forming Fe–F bonds (12% FeF2). The free surface of the nanoparticles, noninteracting with fluorine, is oxidized by oxygen to form Fe2O3 (25%). A model for the structure of the nanoparticles is described.
