无机纳米粒子在电纺丝纤维上的固载及其光催化性能的研究的开题报告 Title: Study on the Immobilization of Inorganic Nanoparticles on Electrospun Fibers and Their Photocatalytic Properties Background: Inorganic nanoparticles, such as TiO2, ZnO, and CuO, have received considerable attention in recent years due to their unique properties, such as high surface area, strong adsorption ability, and excellent photocatalytic activity. These particles have been widely used in environmental remediation, energy conversion, and biomedical applications. However, the application of these nanoparticles is often limited by their poor dispersibility and stability in solution. To overcome these challenges, immobilization of nanoparticles on solid supports, such as electrospun fibers, has been proposed. Objectives: The main objective of this study is to investigate the immobilization of inorganic nanoparticles on electrospun fibers and to evaluate their photocatalytic activity. The specific objectives of this study are: 1. To synthesize inorganic nanoparticles, including TiO2, ZnO, and CuO, with different shapes and sizes. 2. To prepare electrospun fibers of different materials, such as polyvinyl alcohol (PVA), polyacrylonitrile (PAN), and polycaprolactone (PCL). 3. To immobilize the synthesized inorganic nanoparticles on the surface of electrospun fibers. 4. To characterize the morphology, structure, and chemical composition of the electrospun fibers and the immobilized nanoparticles using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). 5. To evaluate the photocatalytic activity of the immobilized nanoparticles under UV and visible light using the degradation of organic pollutants, such as methylene blue and methyl orange. Methodology: 1. Synthesis of inorganic nanoparticles: TiO2, ZnO, and CuO nanoparticles will be synthesized using sol-gel and precipitation methods. 2. Preparation of electrospun fibers: PVA, PAN,
