Outline of Final Research Achievements

Sulfide Co-Precipitation (SCP) method was developed. This method was effective in preparing antimony oxide supported gold catalyst. It was estimated that the size of gold in this catalyst was large by XAFS measurement. No catalytic activity of the supported gold catalyst for CO oxidation was turned out.
KUR was nonoperative because of non-recognition by the Secretariat of the Nuclear Regulation Authority. Au-197 Moessbauer spectroscopy could not be carried out for lack of γ-ray source, Pt-197 which produced by nuclear reactor.
