AB - A series of activated carbons (ACs) were derived from sugarcane bagasse under two activation schemes: steam-pyrolysis at600-800C and chemical activation with H3PO4 at 500C. Some carbons were treated at 400, 60C, or for 1-3 h, and/or inflowing air during pyrolysis of acid-impregnated mass. XRD profiles displayed two broad difuse bands centered around2θ= 23 and 43, currently associated with diffraction from the 002 and 100/101 set of planes in graphite, respectively. Thesed microcrystallite lateral dimensions, La, of the turbostratic (fully disordered)graphene layers. Steam pyrolysis-activated carbons exhibit only the two mentioned broad bands with enhancement in numberof layers, with temperature, and small decrease in microcrystallite diameter, La. XRD patterns of H3PO4-ACs display moredeveloped and separated peaks in the early region with maxima at 2θ= 23, 26 and 29, possibly ascribed to fragmentedmicrocrystallites (or partially organized structures). Diffraction within the 2θ= 43 is still broad although depressed anddiffuse, suggesting that the intragraphiti conditions of chemical activation inflictsinsignificant structural alterations. Circulating air during pyrolysis leads to enhancement of the basic graphitic structure withdestruction and degradation in the lateral dimensions.
