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

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.

Synthesis, Characterization of ZnO/CuO Nanoparticles and Determination of Its Photocatalytic Activity Using 2,6-Dichlorophenol

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.
