Abstract

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 of synthesized ZnO nanoparticles was characterized by XRD, SEM, FT-IR, and UV-vis spectroscopy. The synthesized ZnO nanoparticles indicated particle size with two-type shape. With increased precursor concentration, the ZnO nanoparticles were shown not only increasing from 0.8 to 1.5 μm at primary particles but also similar tendency (15 to 35 nm) at secondary particles. Also, the photocatalytic activities of ZnO synthesized in different precursor concentration was evaluated by removal rate of methyleneblue (MB) under UV irradiation (365 nm) at room temperature. The results showed that the photocatalytic efficiency of ZnO nanoparticles was enhanced by increased precursor concentration.
