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.
