Abstract

We attempt to prepare the patterned electrode for the formation of nano particles using electrochemical deposition with the cathode whose surface has nano dot patterns. In particular, we applied electrodeposition of Pt and UV nano imprinting lithography (UV-NIL) to prepare the nano patterned electrode. In order to achieve higher activity, the deposition condition of Pt was optimized using additives such as polyethylene glycol (PEG). The surface activity of the Pt films was affected by molecular weight of PEG. It was revealed that the surface activity of the films deposited with the order of thousands of molecular weight of PEG indicated the highest effective current density among the examined films. The Pt films, which exhibited the highest current density, were adapted to fabricate nano-patterned electrode with 400 nm pith periodic structure using UV-NIL.
