Evolution of physico-chemical properties of Dicranopteris linearis-derived activated carbon under various physical activation atmospheres

Abstract This work emphasizes the effect of the physical activation using CO2 and steam agents on the physicochemical properties of activated carbon produced from Dicranopteris linearis (D. linearis), a fern species widely distributed across tropic and subtropic ecoregions. The D. linearis-derived c...
