<P>PROBLEM TO BE SOLVED: To reduce the amount of carbon dioxide by reducing/fixing the carbon dioxide, concretely, performing the conversion of the carbon dioxide to oxalic acid by so-called reductive dimerization. <P>SOLUTION: This method for treating the carbon dioxide is provided by preparing a photosynthetic catalyst obtained by covering the surface of titanium oxide by gold fine particles having ≤20 nm particle diameter, and bringing the photosynthetic catalyst in contact with the carbon dioxide under the irradiation of light. The gold fine particles increase reductive potential by accumulating much electron released from the titanium oxide, and thereby reduce the carbon dioxide to form the oxalic acid by obtaining a reduction potential required for the dimerization. <P>COPYRIGHT: (C)2009,JPO&INPIT |
