In this research, we have prepared PAN/PVDF composites via electrospinning. And then, the carbonization and activation process were performed to obtain the porous carbons for carbon dioxide capture (CO2). The features and morphologies were observed by SEM and TEM measurements. The microcrystalline characteristics were measured by XRD, and the surface properties were investigated by XPS. The textural properties were analyzed by N2/77 K adsorption/desorption isotherms. The specific surface area, micropore volume, and pore size distribution were determined by BET, D-R, and NLDFT method. The CO2 adsorption capacities were measured at 298 K. 15% CO2 adsorption capacities were measured by TGA method at specific condition. These results demonstrate the successful fabrication of porous carbons with enhanced CO2 adsorption capacities. Our results indicate that porous carbons are promising adsorbents for CO2 capture |
