摘    要:采用表面活性剂二辛酯琥珀酸磺酸钠(AOT, sodiumbis(2-ethylhexyl)sulfosuccinate)微乳法可以制备得到各种贵金属纳米颗粒(包括银、金、铂以及钯),其性质利用紫外-可见吸收光谱、透射电镜、X-射线衍射、傅立叶变换红外光谱以及Zeta电位分析进行了表征。通过层层自组装方法,将带有负电荷的Pt纳米颗粒和聚阳离子(聚烯丙基氯化铵, PAH)自组装到玻碳电极上,并研究了该修饰电极对甲醇的电催化氧化性质。

关 键 词:Pt纳米颗粒  Zeta电位  负电性质  自组装  电催化反应

Abstract:Silver, gold, platinum and palladium nanoparticles were initially prepared in the AOT [sodium bis(2‐ethylhexyl)‐ sulfosuccinate] micelle and characterized by ultraviolet‐visible spectroscopy, transmission electron macroscopy, X‐ray diffraction, Fourier transform‐infrared spectroscopy, and zeta potential analysis. The negatively charged Pt nanoparticles were self‐assembled on a glassy carbon electrode by a layer‐by‐layer method and the modified electrode electrocatalytic reactivity toward methanol oxidation was studied.
Keywords:Pt nanoparticle  zeta potential  negatively charged  self‐assembly  electrocatalytic reactivity
