【 摘 要 】

In this work LaMnO3- NGP composites with various NGP wt. % were prepared using co-precipitation method. The prepared LaMnO3- NGP composites were characterized by X-Ray Diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area analysis, and Fourier Transform Infrared (FT-IR) spectroscopy. The prepared samples were then used to remove methylene blue (MB) as a model of an organic pollutant under visible light and ultrasonic irradiation separately and simultaneously. The obtained results revealed that the catalytic performance of LaMnO3- NGP composites show better performance than LaMnO3nanoparticles. The photosonocatalytic activity also shows the highest degradation efficiency. Furthermore, the main influence factors on the catalytic activity were studied and discussed.
