Encapsulation of Iron Carbide in Carbon Nanocapsules
نویسندگان
چکیده
Whiskers of iron carbide encased in carbon shells have been prepared from iron(I1) phthalocyanine. Solid FePc is oxygenated and then thermally treated under H2 flow. With proper control of conditions, Fe3C free from metallic iron can be synthesized. The product was characterized with the help of Mossbauer effect spectroscopy, X-ray diffraction, X-ray absorption, and transmission electron microscopy. The iron carbide whiskers range in length from 300 to 500 nm, and their widths are approximately 100 nm. The carbon coating is uniform and about 2.7 nm wide.

Extended Abstract Nanoscale zero-valent iron (nZVI) particles have demonstrated to effectively remove a wide range of pollutants from water, such as chlorinated compounds, heavy metals and dyes. However, the use of nZVI in environmental remediation is limited do to its lack of stability and easy aggregation [1]. nZVI can also deliver the contaminants that had already been adsorbed in their surf...
