Herein an activated carbon (AC) with high surface area and microporosity
was synthesized from the starch-rich mesocarp of the babassu coconut, an
abundant biomass from north and northeastern Brazil. The synthesis of AC
was realized by chemical activation using potassium hydroxide (KOH)
coupled with pyrolysis at 750 degrees C and the produced material was
further characterized by scanning (SEM) and transmission electron (TEM)
microscopy, Fourier transform infrared (FTIR) and Raman spectroscopy,
X-ray diffraction (XRD) and thermogravimetric analysis. SEM and TEM
showed the formation of a thin-layer porous morphology of AC; whereas
the nitrogen (N-2) and carbon dioxide (CO2) adsorption experiments
identified a high surface area and microporosity. Raman spectra obtained
by various laser lines revealed that AC has graphite-like
microstructures with characteristic bands with features dependent on
laser excitation energy. The amorphous nature from AC was further proven
by XRD whereas FTIR showed the presence of surface-active oxygen
functional groups. This AC material, produced from Brazillian Biomass
showed a great potential as a CO2 sensor using a optical technique,
In-situ Raman spectroscopy and their D and G vibrational modes shifting
in the presence of CO2.
