Abstract
Çinko stanat (Zn2SnO4, ZTO) nanoparçacıklar hidrotermal yöntemle 180 °C ve 24 saatte başarılı bir şekilde sentezlenmiştir. Sentezlenen nanoparçacıkların yapısal, morfolojik ve optik özellikleri X-ışını kırınımı, Taramalı elektron mikroskobu (SEM), Fourier Dönüşümlü Infrared Spektrofotometre spektrumu ve UV-Visible spektroskopisi ile karakterize edilmiştir. X-ışını kırınım methodu sonucunda elde edilen pik desenleri incelendiğinde sentezlenen yapının ters kübik spinel formda oluştuğu ve ortalama kristal boyutunun ~22 nm olduğu belirlenmiştir. SEM görüntüleri, sentezlenen nanoparçacıkların küresel morfolojide oluştuğunu göstermektedir. Aynı zamanda sentezlenen Zn2SnO4 nanoparçacıkların Rodamin B (RhB) boyar maddesinin bozunumuna karşı davranışı UV ve görünür ışık altında incelenmiştir. 180 dakikalık yüksek şiddetli UV ışığına maruz bırakılma sonucunda RhB boya çözeltisinin % 82’si bozunurken daha düşük enerjili görünür ışık altında 420 dakikalık ışıma sonucunda da % 86’sının bozunduğu gözlemlenmiştir.
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.
