The catalyst disclosed is a catalyst including palladium-ruthenium alloy fine particles in which palladium and ruthenium form a solid solution. The palladium-ruthenium alloy fine particles used in this catalyst can be produced by a production method including the step of maintaining a solution containing a protective agent, a reducing agent, a palladium compound or palladium ions, and a ruthenium compound or ruthenium ions at a temperature equal to or higher than a predetermined temperature.
摘要:
The three-dimensional structure of the present invention is a three-dimensional structure formed on a base. This three-dimensional structure contains a plurality of porphyrins, a plurality of first metal ions, and a plurality of specific organic molecules. The porphyrin contains two or more functional groups. The first metal ion is a metal ion for linking the functional group of one porphyrin to the functional group of another porphyrin. The above specific organic molecule is an organic molecule that forms a coordinate bond with a metal ion contained in the two-dimensional structure and that has only one site to coordinate to the metal ion.
