Iron Carbide@Carbon Nanocomposites: A Tool Box of Functional Materials.

ABSTRACT: Iron carbide (Fe?C) is a ceramic magnetic material with high potential for applications in different fields, including catalysis, medicine imaging, coatings, and sensors. Despite its interesting properties, it is still somehow largely unexplored, probably due to challenging synthetic conditions. In this contribution, we present a sol-gel-based method that allows preparing different Fe?C@C nanocomposites with tailored properties for specific applications, in particular, we have focused on and discussed potential uses for adsorption of noxious gas and waste removal. Nanocomposites were prepared using readily available and "green" sources, such as urea, simple and complex sugars, and chitosan. The nanocomposite prepared from chitosan was found to be more efficient for CO? uptake, while the sample synthetized from cellulose had optimal capability for dye absorption and waste oil removal from water.
