Carbon capture and sequestration (CCS) is an essential strategy for mitigating greenhouse gas emissions addressing climate change. In this study, the biochar of bamboo orange peel (BB OPB) are synthesized appraised as potential CO2 adsorbents. Comprehensive characterizations viz. sorption isotherm, FTIR spectroscopy, SEM-EDS reveal substantial differences in their structural functional properties. OPB exhibits a significantly higher BET surface area (40.13 m2/g) compared to BBs (7.38 m2/g). EDS analyses further demonstrate more amine, carboxylic, ester, ether groups OPB, indicating its affinity molecules. The adsorption isotherm shows capacity (22.83 cm3/g) than BB (14.12 at 273 K 1 bar. process augmented by mesoporous structures interactions between thermogravimetric analysis reveals uptake capability BB. This result also that stabilizes after 48 h both biochars. These results highlight efficient CCS material, demonstrating importance specific properties development capture.
