PHOTOREDUCTION CATALYST COMPRISED OF RUTHENIUM POLYPYRIDINE COMPLEX SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a means that allows a ruthenium polypyridine complex to function as a practical photoreduction catalyst.;SOLUTION: The ruthenium polypyridine complex is supported on a strong acidic ion exchange polymer. That is, it is the photoreduction catalyst system comprised of the strong acidic ion exchange polymer having the ruthenium polypyridine complex supported thereon, a cobalt polypryridine complex and a solvent. The cobalt polypyridine complex is dissolved in the solvent and the strong acidic ion exchange polymer having the ruthenium polypyridine complex supported thereon is immersed in the solvent. Then, the resultant system is irradiated with visible light and/or ultraviolet light. The system is suitable for reduction of a gas phase oxide such as carbon dioxide.;COPYRIGHT: (C)2003,JPO
