Zamanla, fotokatalizör olarak metal oksitlere olan ilgi artmıştır. Bu çalışmada, ZnO nano yapılı parçacıklar hidrotermal yöntem kullanılarak sentezlenmiştir. Sentezlenen nano yapılı parçacıklar X-ışını kırınımı (XRD) ve taramalı elektron mikroskobu (SEM) teknikleriyle karakterize edilmiştir. Sentezlenen numunelerin fotokatalitik etkileri, metilen mavisi (MM), rodamin B (RB), kongo kırmızısı (KK) ve malahit yeşili (MY) sulu çözeltilerinde 300W ksenon ışığı altında incelenmiştir. Numunelerin fotokatalitik bozunma özellikleri, UV-Vis emilim spektrumlarında (metilen mavisi 664 nm, rodamin B 554 nm, malahit yeşili 617 nm ve kongo kırmızısı 500 nm) ilgili dalga boylarındaki emilimdeki azalmalar hesaplanarak değerlendirilmiştir. Ayrıca, ZnO nanoyapılı parçacıkların metilen mavisi için 80 dakika içinde %99.5, malahit yeşili için 70 dakika içinde %96.5, kongo kırmızısı için 100 dakika içinde %99.8 ve rodamin B için 180 dakika içinde %100 bozunma oranlarına ulaştığı bildirilmiştir. KW - Fotokataliz KW - Bozunma KW - Emilim N2 - Photocatalysis is a promising method for the removal of dye-induced pollution in water using solar energy. Over time, the interest in metal oxides as photocatalysts has increased. In this study, ZnO nanostructured particles were synthesized using the hydrothermal method. The synthesized nanostructured particles were characterized through X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The photocatalytic effects of the synthesized samples were investigated in aqueous solutions of methylene blue (MM), rhodamine B (RB), congo red (KK), and malachite green (MY) under a 300W xenon light. The photocatalytic degradation properties of the samples were evaluated by calculating the decreases in absorption at the respective wavelengths in the UV-Vis absorption spectra (methylene blue 664 nm, rhodamine B 554 nm, malachite green 617 nm, and congo red 500 nm). Furthermore, the ZnO nanostructured particles were reported to achieve degradation rates of 99.5% for methylene blue within 80 minutes, 96.5% for malachite green within 70 minutes, 99.8% for congo red within 100 minutes, and 100% for rhodamine B within 180 minutes.
