PdRu solid solution nanoparticles, method for producing the same and catalyst, method for controlling crystal structure of PtRu solid solution nanoparticles, and AuRu solid solution nanoparticles and method for producing the same
The present invention provides the following three. First, PdRu represented by the formula PdxRu1-x (0.1 ≦ x ≦ 0.8), in which Pd and Ru form a solid solution at the atomic level and have a main structure of a hexagonal close-packed structure (hcp) Provide solid solution nanoparticles. Second, the present invention provides a method for controlling the crystal structure of the PtRu solid solution by controlling the heating temperature of the reducing agent in the PtRu solid solution. Third, Au and Ru represented by the formula AuzRu1-z (0.05 ≦ z ≦ 0.4) are dissolved at the atomic level, and the main structure is a hexagonal close-packed structure (hcp) or face center. AuRu solid solution nanoparticles having a cubic lattice structure (fcc) are provided.
