“…Band near 24° indicates the presence of cellulose in the ACTG 65 . The same pattern of XRD has been shown by Shamsuddin et al 66 The graphite‐like structure typically forms on activated carbon; however, the identical structure in biochar was reported by Bardalai et al 60 with peaks of 3.35 and 2.03 Å that correspond to 2ϴ values of 26.6° and 44.5°. Similar peaks were found in the present study at an interplane spacing (d) of 3.4 and 2 Å corresponding to 26.52° and 44.24° (Table 5).…”

“…The well‐developed porosity and consequent surface boost, with a surface area of 1270 m 2 /g, were preferably driven by the dehydration due to carbonization 52 . Flaky fragments at the magnification of 500 X were observed by Bardalai et al 60 The SEM micrograph finding reported by Nguyen et al 62 showed that the structure of activated carbon was not homogeneous. These characteristics were similar to the activated carbon synthesized in the present analysis.…”

“…Bardalai et al 60 characterized biochar made from teak sawdust and found a peak at 3411 cm −1 showing the existence of the OH group resulting from dehydration of cellulose and hemicellulose present in teak sawdust. Furthermore, bands between 1600 and 1511 cm −1 can be attributed to lignin aromatic vibrations.…”

“…The crystallinity was 8.5% and 91.5% amorphousness in the ACTG depicted lignocellulosic nature of TGSD. Bardalai et al 60 identified an amorphous activity with some local crystallinity in the XRD analysis of biochar prepared from teak tree sawdust. In this study, the amorphous behavior of ACTG was thus established and confirmed by comparison with the work of other researchers.…”

High quality activated carbon was successfully produced from Tectona grandis sawdust by chemical activation using potassium chloride and sodium thiosulphate in a ratio of 1:1.5:1. Surface characterization of sawdust and activated carbon showed the presence of several functional groups such as hydroxyl, ketones, phenols, carboxylic acids, aldehydes and aryl halide together with the heterogeneous surface and extensive porous network as depicted by morphological characterization. It was found that the per cent yield by mass of Tectona grandis sawdust was 52% (SD ± 0.41%). The content of fixed carbon (67.3%) and volatile matter (13.7%) in T. grandis sawdust signifies the ease with which it can be ignited and oxidized. The x‐ray diffraction analysis of activated carbon prepared from T. grandis sawdust indicated amorphous behavior of activated carbon. In the present work, activated carbon possesses 8.76 pH zero‐point charge, 1270 m2/g BET surface area, 0.673 cm3/g total pore volume and 0.42 g/cm3 bulk density.
