Outline of Final Research Achievements

Nanoporous anodic gold oxide film with carbonaceous matter as impurity was formed by anodization of gold in aqueous carboxylic acid such as citric acid. Structure of the gold oxide film was finer than that of nanoporous gold film obtained by anodization in oxalic acid. We also found that the gold oxide film was unstable thus the film was spontaneously reduced to nanoporous gold film. Mean diameter and specific surface area of the nanopores was approximately 7 nm and 60m2g-1, respectively. In case of the anodization in inorganic acid such as sulfuric acid, nanoporous film with pure gold oxide was obtained. The gold oxide film was easily reduced to gold film by cathodic reduction.
