Abstract

Pd nanoparticles were synthesized by reducing PdCl₂ in aqueous or alcoholic solutions in the presence of NaOH or hydrazine hydrate, as well as without them. The palladium powder samples were characterized by X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS) methods. The size of the synthesized Pd nanoparticles varied from ~8 to 28 nm. They were used as a base for the development of catalytically active electrode materials for use in solid polymer fuel cells. The most electrochemically active and stable catalytic electrode materials were determined. Such materials are relevant for use in hydrogen-air fuel cells as an alternative to hydrocarbon fuel.

催化活性钯纳米颗粒燃料电池电极材料的结构研究

在氢氧化钠或水合肼存在和不存在的情况下，通过在水或酒精溶液中还原PdCl2来合成Pd纳米颗粒。采用x射线衍射（XRD）和小角x射线散射（SAXS）对钯粉样品进行了表征。合成的钯纳米粒子的尺寸在~8 ~ 28 nm之间。它们被用作开发用于固体聚合物燃料电池的催化活性电极材料的基础。确定了最具电化学活性和稳定性的催化电极材料。这类材料可用于氢-空气燃料电池，作为碳氢化合物燃料的替代品。
