Optimization of parameters for the synthesis of zinc oxide nanoparticles by Taguchi robust design method

ZnO nanoparticles were synthesized by modified sol–gel process. Taguchi analysis was used in this study and the molar concentration ratio of [LiOH]/[Zn(Ac)2] was the most influencing parameter on the particle size and the size distribution. The optimal conditions were determined by using Taguchi robust design method and nano-sized ZnO particles (∼30 nm) were obtained.
