The Morphology of Biochar Aimed at its Potential Application as an Electrode Material (Batteries, Supercapacitors)

Year: 2025

Type: article

Abstract: This study investigates the properties and potential applications of biochar derived from the pyrolysis of wooden pellets. A detailed physicochemical characterization was performed using scanning electron microscopy (SEM), particle size distribution analysis, Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and elemental analysis. To enhance the surface functionality and introduce oxygen-containing groups that improve hydrophilicity and reactivity, the biochar was chemically modified through oxidation with 30% hydrogen peroxide. Subsequently, the oxidized biochar was doped with graphitic carbon nitride (g-C3N4) to improve its photocatalytic performance and adsorption capacity, leveraging the synergistic interaction between the two materials. The resulting composites were prepared for further use in subsequent research focused on energy-related applications.
