中文摘要:

      借助循环伏安电化学聚合制备了聚苯胺（PANi）/MnT1239卟啉复合材料，再利用还原恒电位沉积法负载铂纳米粒子（Pt NP），最终制备了聚苯胺/MnT1239卟啉/铂纳米粒子复合材料. 电沉积铂之后聚苯胺/MnT1239卟啉材料发生明显样貌变化，棒状结构平均直径从90 nm增加到200 nm，材料具有较大的表面积，空间可负载性好. 铂纳米粒子平均尺寸在20 nm，附着均匀，氧化峰电流在0.2 V处达到7.4 mA，电化学性能优良.

英文摘要:

      The polyaniline/MnT1239 porphyrin/platinum nanoparticle composite was prepared by the cyclic voltammetry electrochemical polymerization of polyaniline/MnT1239 porphyrin composite materials, and the reduction potentiostatic deposition of platinum nanoparticles. Significant changes appeared the polyaniline/MnT1239 porphyrin material after the electrodeposition of platinum: the average diameter of the rod-like structures increases from 90 nm to 200 nm, a large specific surface area, and good spatial loadable ability. The average size of platinum nanoparticles is 20 nm, with homogeneous distribution and great electrical conductivity.
