    摘要: It relates to a method for removing a surfactant, organic materials and chlorine ions remained on the surface of metal nanoparticles, prepared on an organic solvent phase including a surfactant. The method for cleaning metal nanoparticles herein is efficient to remove organic materials or chlorine ions remained on the surface of the nanoparticles. Not less than 90% of impurities may be removed by this method. As a result, the thickness of a multi layer ceramic capacitor (MLCC) can be reduced and a packing factor can be improved so that it allows thinner multi layer ceramic capacitors and improved utilities of metal nanoparticles as fuel cell catalysts, hydrogenation reaction catalysts, alternative catalysts of platinum (Pt) in chemical reactions and the like.
