    • Noble-metal nanoparticles which are metal nanoparticles comprising a noble metal component and further comprise at least one of an organic component containing N and an organic component containing S and have an average diameter controlled to 20 nm or less. A method for producing noble-metal nanoparticles having an average particle diameter of 20 nm or less, which comprises subjecting a noble metal complex compound of quaternary ammonium salt type, represented by the general formula: [R1R2R3R4N]x[My(A) z][wherein R1 to R4 represent the same or different hydrocarbon groups and may have a substituent, M represents at least one noble metal, A represents a thiolate ligand, x represents an integer greater than 0, y represents an integer greater than 0, and z represents an integer greater than 0] to a heat treatment in the presence of an aliphatic amine. The above noble-metal nanoparticles and the above method allow the production of noble-metal nanoparticles excellent in the dispersion stability on a commercial scale.
    • 贵金属纳米颗粒是包含贵金属组分的金属纳米颗粒,并且还包含含有N的有机组分和含有S的有机组分中的至少一种,其平均直径控制在20nm以下。 一种平均粒径为20nm以下的贵金属纳米粒子的制造方法,其特征在于,将通式[R1R2R3R4N] x [My(A)z]表示的季铵盐型贵金属络合物进行处理, [其中R1至R4表示相同或不同的烃基并且可以具有取代基,M表示至少一种贵金属,A表示硫醇盐配体,x表示大于0的整数,y表示大于0的整数,z表示z 表示大于0的整数]在脂族胺存在下的热处理。 上述贵金属纳米粒子和上述方法允许以商业规模制备分散稳定性优异的贵金属纳米粒子。
