Abstract

Farklı
aktif karbon konsantrasyonları ( %5, %10 ve %20) kullanılarak aktif karbon
destekli CdS fotokatalizörler hidrotermal tekniği kullanılarak sentezlenmiştir.
Sentezlenen %5, %10 ve %20 aktif karbon destekli CdS fotokatalizörler sırasıyla
CdS_1, CdS_2 ve CdS_3 şeklinde isimlendirilmiştir. Fotokatalitik deneylerin
birinci aşamasında metilen mavisinin fotokatalitik bozundurulmasında en iyi
fotokatalitik aktiviteye sahip olan fotokatalizör belirlendi. Daha sonra bu
fotokatalizör varlığında, katalizör miktarı ve boya konsantrasyonu gibi farklı
parametrelerin metilen mavisinin fotokatalitik bozundurulmasını nasıl
etkilediği incelenmiştir. Çalışmanın son kısmından en iyi fotokatalitik
aktiviteye sahip olan fotokatalizörün yapısal, morfolojik ve elementsel
özellikleri sırasıyla x-ışını difraksiyonu (XRD), taramalı elektron mikroskobu
(SEM) ve enerji dağıtıcı x-ışını (EDX) cihazları ile karakterize edilmiştir.
