The SEM photographs of the untreated and treated BEFB samples showed rod like structures but while the untreated sample was bundled together the treated samples showed more spaced out structures (Plates 2a & 2b). The alkali treated BEFB sample showed porous structures. In the case of DRFP, the KOH and H3PO4 treated samples showed open porous structures. The untreated sample showed holes that were spaced out on the surface with smooth edges. While the alkali treated samples showed many holes on the carbon surface with broken edges, the phosphoric acid treated samples showed larger pore structures than pore sizes.
