Production of nanoporous carbons from wood processing wastes and their use in supercapacitors and CO2 capture

Highly porous carbons were obtained from solid wastes generated in the chemical and the mechanical processing of birch wood (substandard kraft cellulose, hydrolysis lignin, chips and bark). NaOH-chemical activation of these residues at 575–800 °C resulted in an efficient process to produce carbons w...
