The covalent bromination of multi-walled carbon nanotubes by the reaction with a solution of IBr in CCl4 at mild temperatures and by CH3Br cold plasma is reported. The samples have been analyzed by X-ray photoelectron spectroscopy, thermal programmed desorption, thermogravimetry, Raman spectroscopy, X-ray diffraction and nitrogen adsorption. Both treatments preserve the structure of the nanotubes...
A new method for extensive and homogeneous functionalization of carbonaceous materials with nanostructured nitrogen functionalities is presented. The methodology employed uses a very effective and stable grafting of hyperbranched polyethyleneimines by covalent carboxamide bonds following a sequence of simple, mild, sustainable and easily scalable procedures. The key step in this methodology is the...
A stable, extensive amine functionalization was introduced on the surface of an activated carbon (AC) through very effective grafting of a polyethyleneimine layer onto the AC surface. The procedures used are simple, sustainable and easily scalable. Among the large variety of possible applications that the polyamine functionality confers to the AC, its outstanding properties as Pd(II) adsorbent are...
