Shape-controlled multi-porous carbon with hierarchical micro–meso-macro pores synthesized by flash heating of wood biomass

Effects of raw material texture and activation manner on surface area of porous carbons derived from biomass resources

“…In recent years, various biomass resources (e.g. wood and coconut) have been used as the raw materials for preparation of porous carbons, but the surface areas of the biomass-derived porous carbons are rarely over 2500 m 2 g −1 and the pore sizes are usually distributed in a wide range [23,24]. However, the preparation approach we adopted recently allow for us to obtain biomass-derived porous carbon with a surface area higher than 3200 m 2 g −1 and the pore size distribution of the product is rather uniform [25].…”

Adsorption of bromo-phenol blue from an aqueous solution onto thermally modified granular charcoal

“…An automated adsorption apparatus Quantachrome Nova Win2@1994-2003 was used for these measurements. The specific surface area was determined following the multiple point BET method, micro-pore volume by Dubinin-Radushkevich (D-R) method, and meso-pore volume and pore diameter by BJH method (Kurosakia et al, 2008;Iyobe et al, 2004). The FT-IR spectra of the evacuated GC samples before adsorption were scanned by placing KBr pellets in the Parkin Elmer 16 PC spectrometer.…”

Pore size dependent molecular adsorption of cationic dye in biomass derived hierarchically porous carbon

“…Taking advantage of rich-carbon nature, converting lignocellulosic biomass (raw resources such as wood, cotton or treated resources including cellulose, lignin, tannin and starch) into porous carbon seems a promising approach. For example, wood biomass has been processed into shape controlled hierarchical porous carbon by flash heating method (Kurosaki et al, 2008).…”
