Özet:

 

ZnO powder was synthesized via a hydrothermally assisted   sol-gel method. Synthesis variables including Zn-precursor type, pH value,   time, and temperature of hydrothermal treatment were analyzed using the   Taguchi approach. The experimental procedures were defined based on the L9   array for four variables in three levels. The influences of those variables   on the response parameters, i.e. crystallite size, crystallinity, band gap   energy (Eg)Eg)E_{g}), and degradation constants (k)k)k), were evaluated. XRD results   and EgEgE_{g} values showed that ZnO wurtzite appeared to be the only   crystalline phase in the samples. Taguchi analysis predicted that the   optimized conditions to achieve the highest photoactivity are as follows:   Zn-precursor === zinc acetate, pH === 8, t === 2 h, and T === 150   ∘∘^{\circ}C. The optimized sample was synthesized based on the mentioned   conditions and characterized. The obtained results confirmed the prediction   of the Taguchi method and the highest kkk value was observed.
