Direct electrochemical fabrication of metallic nanopillar array on Au electrode surface by the template technique

摘要

This letter presents a novel, simple approach for direct electrochemical fabrication of metallic (Au or Pt) nanopillar array on gold electrode surface, employing cysteamine as a molecular anchor and anodic aluminum oxide as template without any sputtered metal as electrical conductor. The nanopillar arrays were grew directly on the electrode surface, and the prepared nanopillar array electrodes were used directly and easily to the electrochemical application.
