The base graphitematerial was synthesized by a modified Hummers-Offeman methodusing waste graphite powder, while the metal oxide composites wereprepared by a modified sol-gel method followed by reflux treatment.The synthesized materials were characterized by SEM, XRD, FTIR,N₂ adsorption/desorption analysis, and acid-base analysis, confirmingthat modification with metal oxides led to enhanced surfacedevelopment, changes in pore structure and surface properties, as wellas the formation of functional bonds between the graphite matrix andthe oxide phases. The applicability of the obtained materials wasexamined in the processes of sorption and photocatalysis of thecationic dye Methylene Blue and the anionic dye Reactive Blue 19.The obtained results confirm that the synthesized graphite-dominantcomposites containing metal oxides represent cost-effective,sustainable, and functional materials with significant potential forapplication in the treatment of dye-contaminated wastewater, andshow that the choice of metal oxide dopant determines the selectivityof the composites toward the type of pollutant.
