COMPOSITE TRANSITION METAL CATALYST, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing porous transition metal composite nanoparticles where different kinds of transition metals are evenly combined in the inside, from a mixture of a plurality kinds of transition metal salt by a simple operation with a single process.SOLUTION: A plurality of transition metal species having different reactivity are instantly converted to nanoparticles by accelerating a reaction speed to the limit by rapid heating which is just opposite to an existing methodology. In the conventional methodology, it is common to extremely delay reactivity through addition of surface coating agent/metal ligand or the like in a nucleation/growth stage of nanoparticles in order to eliminate the difference in reactivity of each metal ion. In the reaction, it is possible to achieve rapid combining of primary crystals of several nm or less, available as a catalyst through extreme rapid heating. Furthermore, since various transition metals having a different oxidation-reduction ability are principally applicable, various composite structures can be designed/constituted. It is possible to simply synthesize transition metal composite nanoparticles without the need of a complicated multistep operation.SELECTED DRAWING: Figure 1
