TiO2 ve AgS Katkılı TiO2 Nanotüp Fotokatalizörlerinin Sentezlenmesi ve Karakterizasyonu

Öz

Bu çalışmada, anodik oksidasyon yöntemi kullanılarak yüksek etkinliğe, kimyasal stabilizeye, düşük maliyete ve yüksek yüzey alanına sahip nanotüp TiO2 fotokatalizörleri üretilmiş ve ışık absorbsiyonunu artırmak amacıyla SILAR (Sıralı İyonik Tabaka Adsorpsiyonu ve Reaksiyonu) yöntemi kullanılarak AgS katkılaması yapılarak modifiye edilmiştir. Fotokatalizörlerin yapısal özellikleri SEM ve XRD analizleri kullanılarak karakterizasyonları yapılmıştır. Fotokatalizörlerin kesikli reaktörde fotokatalitik aktivitelerini ölçmek amacıyla Methylene Blue boya çözeltisindeki bozunma incelenmiştir. Elde edilen veriler, nanotüp TiO2’lerinin fotokatalitik aktivitesinin AgS katkısı ile arttığını göstermiştir.

Synthesis and Characterization of TiO2 and AgS Doped TiO2 Nanotube Photocatalysts

Öz

In this study, nanotube TiO2 photocatalysts, have high activity, chemical stabilization, low cost and high surface area, were produced using anodic oxidation method, and modified by doping AgS using SILAR (Sequential Ionic Layer Adsorption and Reaction) method to increase light absorption. The structural properties of the photocatalysts were characterized by SEM and XRD analyzes. In order to measure the photocatalytic activity of the photocatalysts in the batch reactor, the decomposition of Methylene Blue dye solution was investigated. The obtained data showed that the photocatalytic activity of the nanotube TiO2 increased with the doping AgS.
