ZnO Kristalizasyonunun Morfolojisi, Boyut Dağılımı ve Yüzey Alanının Taguchi Deneysel Tasarımı Kullanılarak İncelenmesi

Uzunluk, genişlik ve spesifik yüzey alanı ZnO kristalizasyonunu temsil eden önemli kriterler arasında bulunur. Sentezlenen ZnO kristallerinin ortalama genişliği, ortalama uzunluğu ve yüzey alanı malzemenin kullanılacağı uygulama alanını direkt olarak değiştirdiği için önemlidir. Bu çalışmada bu kriterleri etkileyen faktörler olarak poli(sodyum 4-stirensülfonat) (PSSS) miktarı, ultrasonikasyon gücü, reaktan konsantrasyonu ve reaksiyon sıcaklığı belirlenmiştir. Faktörlerin seçilen kriterler üzerindeki etkileri, Taguchi deney tasarımı yöntemi ve ana etki analizi kullanılarak analiz edilmekte ve tespit edilmektedir. Sonuçlar, Üretilecek ZnO kristallerinin katalizörler olarak kullanımı söz konusu ise, boyut olarak daha küçük ve yüzey alanı daha büyük olan bu kristallerin sentezi için daha düşük PSSS konsantrasyonunun tercih edilmesi gerektiğini göstermiştir. Bir diğer sonuç ise; sentezlenen ZnO kristallerinin ortalama genişlik, ortalama uzunluk ve spesifik yüzey alanı özellikleri üzerinde katkı miktarı ve ultrasonikasyonun en etkili iki parametre olarak karşımıza çıktığı görülmektedir

Investigation of Morphology, Size Distribution and Surface Area of ZnO Crystallization Using Taguchi Experimental Design

Length, width and specific surface area are among the important criteria representing ZnO crystallization. The average width, average length and surface area of the synthesized ZnO crystals are important because they directly change the application area in which the material will be used. In this study, the factors affecting these criteria were determined as the amount of poly(sodium 4-styrenesulfonate), ultrasonication power, reactant concentration and reaction temperature. The effects of the factors on the selected criteria are analyzed and determined using the Taguchi experimental design method and main effect analysis. The results showed that if the ZnO crystals to be produced are to be used as catalysts, a lower PSSS concentration should be preferred for the synthesis of these crystals, which are smaller in size and have a larger surface area. Another result is; It is seen that the amount of additive and ultrasonication are the two most effective parameters on the average width, average length and specific surface area properties of the synthesized ZnO crystals
