In this study, CdS nanoparticles were synthesized in different sizes and morphologies using two different methods. First, the synthesis of both cauliflower-type CdS microspheres and CdS nanoflower-type microstructures by hydrothermal synthesis was carried out in a steel reactors with teflon chamber. While polyethylene glycol and thioacetamide were used in the synthesis of cauliflower-type CdS microspheres, thiourea was used as a sulfur source in the synthesis of nanoflower CdS microstructures. Spherical CdS and Ag/CdS nanoparticles having a diameter of about 200 nm were prepared by the sol-gel method. In this method, polyethylene glycol is used as a stabilizer by providing the control of the growth of nanocrystals due to its high solubility in water and high viscosity. Using both methods, CdS micro- and nanostructures were successfully prepared in different sizes and shapes. These particles were used for photodegradation of methyl orange (MO) dye. The results show that the CdS particles synthesized may have potential uses in waste water applications by photodegrading the MO dye. Energy band gaps of CdS structures were determined by fluorescence spectroscopy measurements. X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) devices have been used to characterize structures. In addition, UV-vis spectrophotometer was used for removal of MO dye from waste water and the percentage of dye degradation and adsorption capacity (qe) of CdS particles were calculated.

 Bu çalışmada, iki farklı metot kullanılarak CdS nanopartikülleri farklı boyutlarda ve morfolojilerde sentezlenmiştir. İlk olarak, hidrotermal sentez yöntemi ile hem karnabahar tipi CdS mikrokürelerin hem de CdS nanoçiçek türü mikroyapıların sentezleri teflon hazneli çelik reaktörlerde gerçekleştirilmiştir. Karnabahar tipi CdS mikrokürelerin sentezinde polietilen glikol ve tiyoasetamid kullanılırken, nanoçiçek CdS mikroyapıların sentezlerinde sülfür kaynağı olarak tiyoüre kullanılmıştır. Diğer bir yöntem olan sol-jel metodu ile de çapları yaklaşık 200 nm olan küresel CdS ve Ag/CdS nanopartiküller hazırlanmıştır. Bu metotta, polietilen glikol su içerisindeki çözünürlüğü ve yüksek viskozitesi sayesinde nanokristallerin büyümelerinin kontrollerini sağlayarak stabilizör olarak kullanılmıştır. Her iki metot ile de başarılı bir şekilde farklı boyutlarda ve şekillerde CdS mikro- ve nanoyapılar hazırlanmıştır. Bu partiküller, metil oranj (MO) boyasının fotodegradasyonunda kullanılmıştır. Ortaya çıkan sonuçlar, sentezlenen CdS partiküllerinin MO boyasının fotodegradasyona uğratarak atık su uygulamalarında potansiyel kullanımları olabileceğini göstermektedir. Floresans spektroskopi ölçümleri ile CdS yapılarının enerji band aralıkları belirlenmiştir. X-ışını kırınım yöntemi (XRD), geçirimli elektron mikroskobu (TEM) ve taramalı elektron mikroskobu (SEM) cihazları yapıların karakterizasyonunda kullanılmıştır. Ayrıca MO boyasının atık sulardan giderim çalışmalarında UV-vis spektrofotometresi kullanılmış olup, CdS partiküllerinin boya degradasyon yüzdesi ve adsorpsiyon kapasitesi (qe) değerleri hesaplanmıştır.
