In order to accurately control the reduction, nucleation and growth process of platinum atoms in the preparation of high purity and high dispersion platinum powder, high purity and high dispersion platinum powder was prepared by chemical liquid phase reduction method with Na₂PtCl₆ aqueous solution as precursor, N₂H₄·H₂O as reducing agent and PVP as dispersant. The effects of temperature, reaction system and feeding method on the morphology, particle size distribution and dispersion of platinum powder were investigated. The results show that the nucleation and growth process of platinum atoms can be effectively separated by using PVP as the dispersion system and Na₂PtCl₆ and N₂H₄·H₂O as the synchronous feeding method at 80 ℃. The high purity and high dispersion micron platinum powder with good dispersion and narrow particle size distribution (D₉₀-D₁₀=1.18 μm) is prepared. This method provides a reliable theoretical basis and technical path for the stable and mass production of high purity and high dispersion micron platinum powder.

为精准控制高纯高分散铂粉制备过程中的铂原子还原、成核与生长过程，研究了采用化学液相还原法，以Na₂PtCl₆水溶液为前驱体、N₂H₄·H₂O为还原剂、PVP为分散剂制备高纯高分散铂粉。考察了温度、反应体系及加料方式等因素对铂粉形貌、粒度分布及分散性的影响。结果表明：在80 ℃条件下，以PVP为分散体系，采用Na₂PtCl₆与N₂H₄·H₂O同步加料的方式，能有效分离铂原子的形核与长大过程，制备出分散性良好、粒度分布窄（D₉₀-D₁₀=1.18 μm）的高纯高分散微米铂粉。该方法为高纯高分散微米铂粉的稳定、批量化生产提供了可靠的理论依据与技术路径。
