摘要

Given the growing demand for nanoscale carbon materials, which possess adsorbent properties and are environmentally friendly, the present work introduces pectin as a new carbon source for synthesizing carbons mesostructured from Korea–3 (CMK-3) with a methodology designed according to the pectin characteristics. The paper presents a comparison between three samples according to their carbon source: (1) sucrose (CMK-3 SAC), (2) Sigma Aldrich analytical grade pectin (CMK-3 PEC-SA), and finally, (3) pectin extracted as agricultural residue from Golden Delicious apple (CMK-3 PEC-RA). The samples were characterized structural, morphological, and texturally by Fourier transform infrared (FTIR) and RAMAN spectroscopies, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N2 physisorption. Pectin structural characterizations allowed the establishment of optimal synthesis conditions. The results showed that CMK-3 synthesized using CMK-3 PEC-RA obtained superior values of specific surface area (1,534 m2/g), pore volume (1.3 m3/g) and mesopores diameters (4.5 nm) with arrangements of homogeneous nanopipes diameters of around 6.5 nm visualized with a fast Fourier transform (FFT) mask than the sample CMK-3-SAC. This fact indicates that using apple waste and its biopolymer pectin may be viable in developing CMK-3 mesoporous carbons with highly specific surface areas for fine chemical processes, considering the previous characterization and homogenization of apple waste.
