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.

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

Abstract

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.
