The article focuses on the electrodeposition noble metals on single-walled carbon nanotubes (SWNTs). The SWNT serves a dual function: initially as the electrodeposition template and subsequently as a wire to electrically connect the deposited Au, Pt and Pd nanoparticles. SWNT electrodes suitable for electrochemical measurements were produced via patterned SWNT growth following standard microfabrication techniques. Metal electrodeposition was performed potentiostatically in a two-electrode arrangement where the deposition potential, duration of the pulse and the concentration of the metal salt (HAuCl4, K,PtCl4, (NH4)2PdCl4) were varied.
