Research Abstract

New evaluation method for characterizing gold cluster catalystswas built using combination between Mossbauer spectroscopy and X-ray absorption spectroscopy. It was useful in the various system for gold catalysts, at the standpoint of judging whether or not gold cluster was present, and distinguish valence of gold. It is necessary to secure a lot of storage space because of the instability of gold cluster. In this study, Metal Organic Frames(MOF) and Nickel metal as storage space could stabilize small gold clusters and gold atoms, respectively.
