摘要
Manganese oxide (MnO) colloidal nanoneedles have been successfully synthesized by a facile one-step method based on the alkaline reaction of the precursor manganese acetate salt and excess sodium hydroxide. X-ray diffraction and FT-IR spectroscopy confirmed the synthesized MnO nanoneedles phase and structure. The optical properties of synthesized MnO nanoneedles were studied by UV-Vis absorption spectroscopy. Optical particle size and band gap of synthesized MnO colloidal nanoneedles were calculated. HR-TEM/SEM images and EDX allow us to determined particle shape and size. The photocatalytic activity of the MnO nanoneedles was evaluated using the Congo red azo dye in an aqueous solution under solar light irradiation. The results showed that nanoneedles, compared with commercial ZnO nanoparticles, exhibited high photocatalytic activity. The photocatalytic studies also showed that various parameters such as band gap, size, shape, and rate constant velocity remarkably affected the remotion rate of Congo red azo dye.
