Název v původním jazyce

UV-activated TiO2-coated carbon felt for photocatalytic dye degradation and antibacterial applications

Popis výsledku v původním jazyce

Photocatalysis has been widely applied in dye degradation due to its high efficiency, stability, and environmental friendliness. However, the challenge of separating catalysts from aqueous systems persists, driving the demand for highly stable, durable, and cost-effective catalyst carriers. In this work, carbon felt prepared from waste acrylic fiber felt was used as a TiO2 carrier for the photocatalytic degradation of dyes. To immobilize TiO2 particles on the surface of the carbon fibers, a copolymer containing benzophenone groups was used to establish covalent bonds between the fibers and the particles through UV irradiation. The coated material exhibited high photocatalytic efficiency, achieving 95% degradation of Orange II dye within 180 minutes under UV light, following pseudo-first-order kinetics. Furthermore, the coated carbon felt demonstrated remarkable antibacterial performance, completely eliminating Escherichia coli and Staphylococcus aureus colonies within 24 hours. Durability tests indicated excellent resistance to washing and UV exposure, maintaining structural and functional integrity after prolonged use. This approach provides a low-cost method to develop chemically stable and durable TiO2 carriers, offering a sustainable solution for textile dye wastewater treatment.
