Sol-Jel Yöntemiyle Sentezlenen CeO2:0.1Er0.1Y Bileşiğinin Farklı Boyalar İle Fotokatalitik Aktivitelerinin İncelenmesi
Öz
Bu çalışmada, güneş enerjisi yardımıyla CeO2 temelli fotokatalizör bileşiğinin farklı boyar madde üzerinde etkisi araştırıldı. Çalışmada endüstride sıkça kullanılan ve toksik etkiye sahip metilen mavisi ve malahit yeşilinin CeO2:0.1Er0.1Y bileşiği kullanılarak fotokatalitik bozunma davranışı incelendi. Fotokatalizör, sol-jel yöntemi kullanılarak Er ve Y elementlerinin CeO2 kristal yapısına birlikte katkılaması ile sentezlendi. Sentez sonrası kristal yapı tayininde x-ışını toz difraktometresi kullanıldı. Sentezlenen örnekler kübik kristal yapısına sahiptir. Fotokatalizör etkinliklerinin araştırılmasında süreye bağlı olarak boya giderimi UV-Vis spektrofotometre ile izlendi. Boya giderim mekanizmasının detaylı incelenmesi amacıyla FT-IR analizinden yararlanılmıştır. Sonuç olarak, CeO2:0.1Er0.1Y bileşiğinin optik bant enerji düzeyi 2.92 eV hesaplandı. Sentezlenen CeO2 tabanlı bileşiğin fotokatalitik verim sırasıyla malahit yeşili ve metilen mavisi için % 48 ve %37 olarak belirlendi.

Investigation of Photocatalytic Activities of CeO2:0.1Er0.1Y Compound Synthesized by Sol-Gel Method with Different Dyes
Öz
In this study, the effect of CeO2-based photocatalyst compound on different dye was investigated with the solar energy. In the study, the photocatalytic degradation behavior of methylene blue and malahit green, which are frequently used in industry and have toxic effects, was investigated by using CeO2:0.1Er0.1Y compound. Photocatalyst was synthesized by doping Er and Y elements together to CeO2 crystal structure using sol-gel method. X-ray powder diffractometry was used to determine the crystal structure after synthesis. The synthesized samples have a cubic crystal structure. In the investigation of photocatalyst activities, dye removal was analysed with UV-Vis spectrophotometer. FT-IR analysis was used to examine the dye removal mechanism in detail. As a result, the optical band energy level of CeO2:0.1Er0.1Y was calculated as 2.92 eV. The photocatalytic efficiency of the synthesized CeO2-based compaund was determined as 48% and 37% for malehide green and methylene blue, respectively.
