    • 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. 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.

    • 要解决的问题:为了通过还原/固定二氧化碳来减少二氧化碳的量,具体地,通过所谓的还原二聚将二氧化碳转化为草酸。 解决方案:通过制备通过用≤20nm粒径的金微粒覆盖氧化钛表面而得到的光合催化剂,并使光合催化剂与二氧化碳接触的方法来提供这种二氧化碳处理方法 光的照射。 金微粒通过累积从氧化钛释放的大量电子而增加还原电位,从而通过获得二聚化所需的还原电位来减少二氧化碳以形成草酸。 版权所有(C)2009,JPO&INPIT
