碩士 === 國防大學中正理工學院 === 應用化學研究所 === 91 === A novel technique of preparing metallic nanoparticles based on the concept of electroless plating was investigated. Ni-P alloy nanoparticles were prepared in an aqueous solution, using nickel sulfate as the precursor, sodium hypophosphite as the reducing agent and palladium chloride as the nucleation agent. Experiment results revealed that use of stabilizer such as lead nitrate or potassium iodiate is effective in restrain grow of nanoparticle. Experiment results also revealed that cetyltrimethylammonium bromide (CTAB) is capable of preventing Ni-P alloy nanoparticles from agglomeration. Ni-P alloy nanoparticles with minimum diameter 2nm under optimal condition were formed and verified by transmission electron microscope images. Furthermore, the Ni-P ultrafine powders by this process were attempted to recycle nickel ion from electroless plating waste water and it showed that waste plating water treatment with this process can recycle nickel ion rapidly and effectively.
