Patterning of metallic nanoparticles (NPs) via BC micelles plays an important role in the manufacture of conductive integrated devices. BCs containing a metal-binding block of poly(vinylpyridine) (P2VP or P4VP) can be used as a direct chemical reagent to coordinate to or to be protonated by metal ions and compounds such as chloroplatinic acid (H₂PtCl₆) or auric acid (HAuCl₄). In this work, Platinum nanoparticles (Pt NPs) were synthesized by dip-coated technique on titanium wafers. The dip-coating withdrawal rate and concentration of H₂PtCl₆ precursor had been investigated as two of most important factors on the morphology of Pt-NP arrays. The result shows that diameter of nanodots decreases with the increase of withdrawal rate. The initial ECSA and durability of the Pt/Ti catalysts, with an initial ECSA of 106.5 m².g^-1 and a nearly zero particle-aggregation during 3000-cycle CV, can be controlled through particle size and spacing.
