Abstract :
Cauliflower-like nanostructure of cadmium oxide was synthesized by
utilizing mechanochemical reaction followed calcination procedure
for the first time. The design of experiment (DOE) by Taguchi
method was used to study influence of the chosen factors and to
consider optimum conditions of the experiments. The temperature of
calcining, the duration of milling, the duration of calcining and
reactants molar ratio (M/L) are four chosen factors for DOE. The
value of band gap energy was calculated through UV-visible
absorption spectroscopy and Tauc relation. Data analysis was
performed using Minitab and Qualitek-4 statistical softwares. The
optimum conditions for preparing cauliflower-like structure were
predicted and also, influence of each factor was determined. The
temperature and duration of calcining with the percentage
contribution of 68.23 and 17.72%, respectively are the most effective
factors at this design.
