Abstract

The aim of the present work is to follow the capacity of adsorption of CO₂ by natural cellulose nanofibers, extracted from banana peel and mixed with nano-silver. Following initial characterization, the raw material and the isolated sample were investigated by Energy Dispersive Analysis (EDS), X-ray diffraction (XRD); Fourier- Transformed infrared spectroscopy (FT-IR) and thermal analysis (Hi Res TG). Nitrogen gas adsorption-desorption isotherms of isolated cellulose nanofibers reveal a type I- isotherm, specific to the nano-porous materials.The results of adsorption isotherms of CO₂ at 304 K showed that the extracted sample exhibit an adsorption capacity of 12 mmol/g of CO₂.
