27 - Fourier-transform infrared and UV-visible spectral characterization of biomass-derived conductive carbon
Description/Abstract/Artist Statement
Biomass-derived carbon materials were investigated for their potential as multifunctional materials with tunable electronic and surface properties. White Oak wood biomass was thermally processed and mechanically milled under controlled conditions to produce three distinct carbon batches. Each batch was characterized using Fourier-transform infrared and UV-visible spectroscopies to determine the chemical structure and optical characteristics relevant to applications in sensing, electronics, and protective coatings. Fourier-transform infrared spectroscopy spectral analysis revealed distinct functional groups for each sample. White Oak Carbon samples A2 and A3 exhibited N–H stretching frequencies at 3313 cm⁻¹ and carbonyl C=O stretching frequencies at 1632 cm⁻¹. The nitrogen-doped White Oak Carbon sample B4 demonstrated additional peaks corresponding to N–H stretching frequencies at 3358 cm⁻¹, aliphatic C–H stretching frequencies around 2972 cm⁻¹, and C=O stretching frequencies at 1647 cm⁻¹, thus confirming successful nitrogen incorporation and increased chemical complexity. UV-visible spectroscopy identified characteristic absorption peaks, with White Oak Carbon samples A2 and A3 showing prominent wavelengths at 197 nm and 194 nm, respectively. The nitrogen-doped sample B4 displayed absorption wavelengths at 199 nm and an additional peak at 292 nm. Notably, all samples exhibited a consistent absorption in the 900-1000 nm range, indicative of potential metal-containing electronic transitions. These functional groups and optical properties supported the integration of biomass-derived conductive carbon into advanced technological applications. Future research will focus on electrical characterization and structural imaging to further explore the suitability.
