GRAPHITIZED MATRIX NANOCOMPOSITES AND METAL NANOPARTICLES WITH SUPERCAPACITANCE AND MAGNETORESISTANCE PROPERTIES

摘要

The present invention relates to nanocomposites based on graphitized and porous carbon forms wherein metal nanoparticles in zero oxidation state are embedded. Furthermore, it also relates to the preparation process of said nanocomposites, initiated with the synthesis of a layered hydroxide as precursor and the subsequent calcination thereof in very mild temperature conditions. The nanocomposite thus produced has supercapacitance and magnetoresistance properties, which make it suitable for different applications in energy storage, in electronics and in spintronics.
