Preparation of Activated Carbons from Cork by Physical Activation in Carbon Dioxide
Adsorption Science & Technology, 2003 Activated carbons (ACs) were prepared by the physical activation of cork wood, virgin cork and adult cork of different particle sizes in carbon dioxide and characterised by elemental analysis, DRIFTS, SEM and N2 adsorption at −196°C. The wood gave results similar to those obtained with other lignocellulosic precursors.
