HİDROTERMAL YÖNTEMLE SENTEZLENEN ÇİNKO STANAT (Zn2SnO4) NANOPARÇACIKLARIN FOTOKATALİTİK PERFORMANSLARININ İNCELENMESİ

Çinko stanat (Zn2SnO4, ZTO) nanoparçacıklar hidrotermal yöntemle 180 °C ve 24 saatte başarılı birşekilde sentezlenmiştir. Sentezlenen nanoparçacıkların yapısal, morfolojik ve optik özellikleri X-ışınıkırınımı, Taramalı elektron mikroskobu (SEM), Fourier Dönüşümlü Infrared Spektrofotometre spektrumuve UV-Visible spektroskopisi ile karakterize edilmiştir. X-ışını kırınım methodu sonucunda elde edilenpik desenleri incelendiğinde sentezlenen yapının ters kübik spinel formda oluştuğu ve ortalama kristalboyutunun ~22 nm olduğu belirlenmiştir. SEM görüntüleri, sentezlenen nanoparçacıkların küreselmorfolojide oluştuğunu göstermektedir. Aynı zamanda sentezlenen Zn2SnO4 nanoparçacıkların RodaminB (RhB) boyar maddesinin bozunumuna karşı davranışı UV ve görünür ışık altında incelenmiştir. 180dakikalık yüksek şiddetli UV ışığına maruz bırakılma sonucunda RhB boya çözeltisinin % 82’sibozunurken daha düşük enerjili görünür ışık altında 420 dakikalık ışıma sonucunda da % 86’sınınbozunduğu gözlemlenmiştir.

Investigation of Photocatalitic Performance of Zinc Stanate (Zn2SnO4) Nanoparticles Synthesized by Hydrotermal Method

Zinc stanate (Zn2SnO4, ZTO) nanoparticles were successfully synthesized by hydrothermal method in 180 °C and 24 hours. Structural, morphological and optical properties of synthesized nanoparticles were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier Transform Infrared Spectrophotometer and UV-Visible spectroscopy. When the XRD was used, the inverted cubic spinel structure was determined with ~ 22 nm the mean crystal size. According to the SEM images, the nanoparticles have spherical morphology. At the same time, the behavior of synthesized ZTO nanoparticles against degradation of Rhodamine B (RhB) dye was investigated under UV and visible light. As a result of exposure to 180 minutes of high intensity UV light, 82% of the RhB dye solution was degraded, while 86% degradation was observed as a result of 420 minutes of radiation under lower energy visible light.
