METHOD FOR PRODUCING ALLOY CARRYING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an alloy carrying material in which alloy particles are supported in a highly dispersed state.SOLUTION: There is provided a method for producing an alloy carrying material in which alloy particles composed of at least two kinds of metals selected from elements of Group 3 to 13 in the periodic table, which comprises: a step of dispersing the carrier in a reducing solvent to prepare a carrier dispersion reducing solvent; a step of preparing an aqueous solution containing at least two kinds of metal ions which are a precursor of the alloy particles; a step of spraying the aqueous solution in the carrier dispersion reducing solvent while heating the carrier dispersion reducing solvent; and a step of performing reduction treatment and alloying of metal ions by maintaining heating of the carrier dispersion reducing solvent.SELECTED DRAWING: Figure 1
