Characterization of activated carbon produced from industrial waste of yerba mate by chemical activation with ZnCl2

Year: 2024

Type: article

Abstract: In this study, activated carbons (ACs) were prepared by chemical activation with ZnCl2 of yerba mate (YM) branches in a ratio of 1:1 mass of carbon vs. mass of activating agent, performing the pyrolysis at 550, 650, and 750°C in a stream of nitrogen for 60 and 120 minutes. The resulting AC were characterized by various techniques, such as Brunauer-Emmett-Teller (BET) analysis, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD) to confirm its characteristic properties. The surface area and pore volume of the resulting ACs decreased with increasing temperature. The samples obtained at 650°C of treatment have the maximum BET-specific surface area of 940 m2 g-1.
