Magnetic Carbon

Carbon nanocomposites microspheres were synthesized from Low-Density Polyethylene (LDPE) by a facile one-step strategy under solvent-free conditions. The synthesis of these materials was carried out in a closed Hastelloy® reactor at 700 °C. The treatment, during which autogenic pressure was generated, leads to highly graphitic materials with stunning properties, particularly concerning the oxidation resistance (compared to the graphite stability). The metallic doping triggers the growth of nanostructures with diverse morphologies around the spheres, obtaining samples with magnetic properties.

Commercially available zirconia (ZrO2) is reported as an extremely efficient catalyst for the synthesis of quinolines. A one-step reaction of 2-aminoarylketones and a carbonyl compound (Friedlander reaction) took place under solvent-free conditions to afford the corresponding quinolines in good-to-high yields in the presence of ZrO2. Furthermore, the catalyst is reused several times without any significant loss of its catalytic activity.
