“…The intra-particle diffusion kinetics model indicates the CO2 adsorption process in the SBAN pore takes place in two stages, namely the mesopore diffusion stage and the micropore diffusion stage. At the mesoporous diffusion stage, CO2 gas molecules are adsorbed on amorphous carbon on the outer surface of SBACN, while at the micropore diffusion stage, CO2 gas molecules will be deposited on the surface in the SBACN which enters the carbon pore [34] [37].…”

“…The plot between qt as ordinate and t 1/2 as abscissa as shown in Figure 5 (c) is a graph of intra-particle diffusion. Based on Figure 5 (c), the initial process or mesoporous diffusion is rapid which then slows down when diffusing into the surface of micropore diffusion on SBACN nitrogen which enters the carbon pore [34] [37].…”

Nitrogen-doped activated carbon (SBACN) was synthesized from sugarcane bagasse waste as acarbon source and urea as nitrogen source through potassium hydroxide (KOH) activation for 2 h at high temperature via two step methods. The synthesized SBCN was characterized using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Fourier Transform Infrared (FTIR). The results showed that the SBCN has low degree crystallinity and graphitization with highly developed micropores due to synergistik activation effect of KOH and urea. These characteristics provide an important contribution to carbon dioxide adsorption capacity, which can reach up to 11,20% wt and this value is higher than pristine activated carbon. The results indicating that the presence of this nitrogen functionalities is found to have a beneficial influence on the carbon dioxide adsorption characteristic in standart condition and exhibit considerable potential in solid adsorption.
