Перспективы развития фундаментальных наук. Т. 2 : сборник научных трудов XV Международной конференции студентов, аспирантов и молодых ученых, 24–27 апреля 2018 г Т. 2 : Химия. С. 69-71Abstract: Nano-sized ZnO powder was prepared via a pulsed laser ablation of metallic zinc target in air atmosphere and modified with AgNOs to form ZnO/Ag for improving the photocatalytic activity. All samples was dried and calcined at 60, 300 and 500 °C. The photocatalytic activity of obtained powders was evaluated by measuring the degradation of Rhodamine C dye in water under UV-visible light region. Nanopowders were characterized by XRD, SEM, ТЕМ, and UV-vis spectroscopy. It was found that calcined ZnO demonstrate less photocatalytic activity than initial powder, and Ag-modified ZnO is more active than pure ZnO due to improved absorption of light in visible region.
