This study describes the production of low-cost and eco-friendly carbon nanorod films from lignin biomass feedstock and examines their compositional, structural, optical, and gas-sensing properties. The carbon nanorods were obtained through the electrospinning of lignin/PVA solutions with varying iron oxide concentrations (4, 5, and 7 ppm) and subsequent 600°C carbonization in a nitrogen atmosphere. The structural and morphological characteristics of the resultant films were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and photoluminescence (PL) spectroscopy.
