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.
