摘要：
A study was conducted to demonstrate the successful nanostructuring of an Au(111) electrode surface with Fe clusters in a 1-butyl-3-methyl-imidazolium tetrafluoroborate (BMI-BF4) ionic liquid, which provides the basis for the studies of new nanoscopic effects of Fe, for investigating the electrochemical properties of nanoscalic Fe. Complex patterns and large-scale ordered arrays of Fe nanoclusters, several monolayers in height, have been fabricated with high precision and high electrochemical stability. The present work provides the basis for surface engineering with Fe nanoclusters by electrochemical means and with a variety of possibilities. The magnetic Fe or Fe oxide nanoclusters may be used as templates for constructing other magnetic nanoparticles. Extending Fe nanostructuring onto surfaces such as Pt and Cu provides systems even more interesting for catalysis and surface science.
