Surface and porous characterisation of activated carbons made from a novel biom...
Nabais, Joao; Laginhas, Carlos; Ribeiro Carrott, Manuela; Carrott, Peter; Crespo Amoros, Jose; Nadal Gisbert, AntonioIn the work now reported the production of activated carbons from a novel precursor, esparto grass, by activation with carbon dioxide is presented. The results show that the materials produced have interesting properties, namely BET apparent surface area and pore volume up to 1122 m2 g−1 and 0.46 cm3 g−1, respectively. The activated carbons have basic characteristics with point of zero charge between 9.25 and 1...
Characterization of the Surface of Activated Carbons Produced from Tire Residues
Valente Nabais, Joao; Laginhas, Carlos; Carrott, Peter; Carrott, Manuela; Galacho, Cristina; Crespo Amoros, Jose; Nadal Gisbert, AntonioThe surface characterisation of new activated carbons produced from tire residues by activation with carbon dioxide was studied. The activated carbons produced were mainly basic with point of zero charge values above 8.8. The main surface functional groups identified by FTIR were ether, quinones, lactones, ketones, hydroxyls (free and phenol) and pyrones. The XRD analysis shows that the materials produced have ...
