IRON DOPED CARBON AEROGEL AS CATALYST FOR PHENOL TOTAL OXIDATION. Authors: ANDRADA MĂICĂNEANU, COSMIN COTEŢ, VIRGINIA DANCIU, MARIA STANCA. |

Abstract: Two types of iron doped carbon aerogels were prepared by sol-gel polymerization of potassium salt of 2,4-dihydroxybenzoic acid with formaldehyde. This process was followed by an ion-exchange process between K+ doped wet gel and Fe(II) or Fe(III) ion aqueous solutions. The resulted Fe(II) or Fe(III) doped gels were dried in supercritical conditions with liquid CO2 and then pyrolyzed when two types of iron carbon aerogels were obtained. These aerogels were morpho-structural investigated by means of transmission electron microscopy (TEM), X-ray diffraction (XRD), specific surface area determination using nitrogen adsorption (BET and BJH methods) and elemental analysis. Iron doped carbon aerogels were tested as catalytic materials in phenol wet air oxidation process (total oxidation). Temperature, air flow, catalyst quantity and phenol concentration over the removal efficiency of the organic compound was studied.
Keywords: iron doped carbon aerogel, phenol, catalytic wet air oxidation |
