This study explores the transformation of peanut shells, an abundant agricultural waste, into high-efficiency activated carbon for CO2 capture using a two-step pyrolysis and K2CO3 activation method. Observations indicated that with an increasing impregnation ratio, the activated carbon demonstrates remarkable improvements in structural properties, achieving specific surface areas and pore volumes of 1150.02 m2/g and 0.46 cm3/g, respectively. Among the prepared samples, the activated carbon obtained with a peanut shell to K2CO3 impregnation mass...
