Impact of pH on zinc oxide particle size by using sol-gel process
Zinc oxide (ZnO) nanoparticles were prepared and synthesized via sol-gel method, by using citric acid as a precursor. The annealing temperature was fixed at 600°C. The impact of pH on the particle size was investigated. Based on the results from the Thermogravimetric Analysis (TGA), three different...
