A Comparison of Two Methods for the Development of Low-Cost Carbonaceous Adsorbent from Rubber-Seed Shell (RSS)

Biomass-derived porous carbons have recently gained much attention for carbon dioxide (CO2) adsorption. In this work, RSS were used as a precursor to prepare highly porous activated carbon (AC). RSSAC was synthesized through the conventional two-stage chemical activation as well as through a new thr...

The SEM images of RSSAC revealed a highly porous structure. From the elemental composition analysis, carbon (77) and oxygen (18) were the major elements found in RSSAC.
