摘要：NOVELTY - Preparation of monocrystalline spherical silver nanoparticles involves dispersing silver nanoparticles in colloidal solution of silver nitrate, polyvinyl pyrrolidone and organic solvent, adding isopropyl alcohol, ethanol, deionized water, aqueous ammonia and tetraethoxysilane to form dense silicon dioxide layer on silver nano particle surface, freeze-drying, placing in tubular furnace, calcining under inert atmosphere at 800-1000 degrees C, adding sodium hydroxide, diethylamine and deionized water, and removing silicon dioxide layer. USE - Method for preparing monocrystalline spherical silver nanoparticles (claimed).
