Abstract
Interconnected porous monolithic materials can be directly obtained from non-templating methods by reacting raw Kraft black liquor with epichlorohydrin either in the presence or not of surfactant, whereas extracted lignin leads to non-porous materials. In the presence of a surfactant, micelles organization takes place and porosity of 40–60% can be achieved. Without surfactant, chemically induced phase separation occurs, giving materials with agglomerated nodules morphology. Carbonization followed by activation with CO2 yield monolithic micro/mesoporous carbons with surface area of 300 m2 g−1.
