Abstract：To meet the production requirements of a new generation of high-precision platinum alloy electrodes,the micro-size,morphology and crystal face of platinum alloy particles were regulated by adjusting the heat treatment process parameters.The micro-nano structure of the electrodes was optimized fundamentally,and the induction effect of temperature on the high-index crystal face of the alloy was clarified.The electrical properties of the single electrode were characterized,and the mass and specific activities of the platinum alloy electrode were calculated according to the relevant activity and kinetic mathematical model.The results showed that the platinum alloy obtained by heat treatment at 700℃ showed the highest activity(0.71 A/mgPt and 0.32 mA/cm2).At the same time,in order to ensure the development of excellent mass transfer quality and high stability electrode,the composite process parameters of the electrode were adjusted,and the treatment method of layer by layer rotating spraying was adopted to improve the forming and manufacturing of the efficient platinum alloy electrode and ensure the improvement of the overall electrical performance.The resulting platinum alloy electrode showed a high power density(231 mW/cm2).
