Abstract
The removal of methylene blue solutions was carried out with photocatalytic reaction using zinc oxide nanoparticles. Zinc oxide nanoparticles were synthesized by polyol method and characterized by XRD, SEM, TEM, and UV-DRS. The characterization results showed that zinc oxide nanoparticles have a hexagonal prismatic structure, with particle size around 40-100?nm, particle aggregation formed, and the band gap energy (Eg) is 3.2 eV. Zinc oxide nanoparticles were tested for their photocatalytic activity for the removal of methylene blue at solution concentration of 20?mg.L-1 under UV-LED irradiation. The removal of methylene blue solutions using zinc oxide nanoparticles showed the rates 0,07?mg.L-1.minutes-1. The biggest methylene blue concentration removal by zinc oxide nanoparticles was 98,00% with a time of 50 minutes under UV-LED irradiation.
