In this research, ZnO nanoparticles were synthesized by spray-pyrolysis method using the zinc acetate dihydrate as starting material at synthesis temperature of 900°C with various concentrations (0.01, 0.1, 1.0 M, respectively). The physico-chemical property was characterized XRD, SEM, FT-IR, and UV-vis spectroscopy. indicated particle size two-type shape. With increased precursor concentration, shown not only increasing from 0.8 to 1.5 μm primary particles but also similar tendency (15 35 nm) secondary particles. Also, photocatalytic activities in different concentration evaluated removal rate methyleneblue (MB) under UV irradiation (365 room temperature. results showed that efficiency enhanced concentration.
