    The Photocatalytic Performance of Ag /TiO2/Nylon 6/PMMA System
    (Springer Heidelberg, 2024) Polat, Kinyas; Bursali, Elif Ant; Yurdakoc, Muruvvet; Yurdakoc, Kadir
    Herein, Ag/TiO2/Nylon 6/PMMA catalyst system was developed, and its photocatalytic properties were fully analyzed. XRD, SEM, EDS, and PL analyses were carried out to get information on crystal structure, micromorphology, elemental composition, and band gap energy. Photocatalytic degradation was followed by UV-vis spectrophotometry. The band gap of the catalyst was found to be between 2.51 and 3.1 eV. Up to 80% degradation was achieved under UV light irradiation. No bulk adsorption was observed, which means that the reaction was completely carried by the photocatalytic process. pH 3 value was determined to be suitable for a high rate. Reaction kinetic was determined to be matched with the first-order rate law. The newly developed polymer blend matrix system here may have broad application prospects in the remediation of water resources.

    ZnO/PMMA Nanofibers for the Photocatalytic Water Remediation
    (Springer/Plenum Publishers, 2025) Polat, Kinyas; Bursali, Elif Ant; Yurdakoc, Muruvvet
    In this study, a novel ZnO/PMMA nanofiber catalyst was fabricated using electrospinning, resulting in a barbed wire-like structure that enhances photocatalytic performance. The research aimed to investigate the material's effectiveness in degrading organic pollutants under UV light, providing a sustainable solution for water purification. Comprehensive characterization techniques, including XRD, XPS, SEM, EDS, and FTIR, were employed to analyze the crystal structure, micromorphology, and elemental composition of the catalyst. Photocatalytic degradation experiments showed that up to 91% degradation was achieved after 60 min of UV light irradiation at pH 11, with no significant bulk adsorption observed, confirming the dominance of the photocatalytic mechanism. The optimized pH of 11 was found to be ideal for achieving high degradation rates. This novel ZnO/PMMA nanofiber structure demonstrates significant potential for environmental applications, particularly in water purification, offering an efficient and sustainable approach to pollutant removal.
