Abstract

In this study, The studies on the degradation of
2,6-dichlorophenol (2,6-DKF), which is highly toxic to the ecological
direction, were carried out using different catalysts. SEM analyzes showed that
the synthesized particles were close to the spherical morphology. XRD analyzes
show that the ZnO and CuO have smaller shifts in the characteristic 2θ values
in ZnO/CuO composite structure. The BET surface area of composite ZnO / CuO
particles was found to be higher than bare ZnO and CuO catalysts. The findings
of the photocatalytic studies show that the composite particles are more
effective than the pure ones because of the synergistic effect and the
structural properties of the two catalysts in the composite structure.

ZnO/CuO Nanopartiküllerinin Sentezi Karakterizasyonu ve Fotokatalitik Aktivitesinin 2,6-Diklor Fenol Kullanılarak Belirlenmesi

Abstract

Bu çalışmada ekolojik
yönden son derece toksik olan 2,6-diklorfenolün (2,6-DKF) farklı katalizörler
kullanılarak bozunmasına ait çalışmalar yapılmıştır. SEM analizleri sentezlenen
partiküllerin küreselliğe yakın bir morfolojide olduğunu göstermiştir. XRD
analizleri kompozit halde iken ZnO ve CuO’nun karakteristik 2θ değerlerinden
daha büyük açılara kaymaların olduğu göstermektedir. Kompozit ZnO/CuO
partiküllerinin BET yüzey alanının ZnO ve CuO’dan daha yüksek olduğu
gözlemlenmiştir. Fotokatalitik çalışmalarda elde edilen bulgular kompozit
ZnO/CuO partiküllerinin yalnız ZnO ve CuO’ya göre daha etkin olduğu, bu
etkinliğin her iki katalizör kompozite halde iken aralarında oluşan sinerjitik
etkiden ve yapısal özelliklerden kaynaklandığı düşünülmektedir.
