Procedure

2 g of the PPy-C dry powder obtained in step 1) was added to 44 mL of pure water, and the mixture was stirred for 30 minutes while being heated up to 80° C., so that a PPy-C dispersion liquid having PPy-C dispersed therein was obtained. Subsequently, 1.1 g of cobalt nitrate (II) hexahydrate was dissolved in 11 mL of pure water to prepare an aqueous cobalt-containing solution. Then, the aqueous cobalt-containing solution was added to the PPy-C dispersion liquid and the mixture was stirred at 80° C. for 30 minutes to thereby produce a cobalt-PPy-C-mixed solution. Subsequently, 5.23 g of sodium borohydride and 0.37 g of sodium hydroxide were dissolved in 500 mL of pure water to prepare an alkaline aqueous solution. Next, the alkaline aqueous solution was gradually added to the cobalt-PPy-C-mixed solution until the cobalt-PPy-C-mixed solution had a pH of 11.1, and thereafter, the cobalt-PPy-C-mixed solution was allowed to stand at 80° C. for 30 minutes. All the operations that led up to the operation (operation of adding the alkaline aqueous solution) in step 2) were performed under a nitrogen atmosphere. Thereafter, the cobalt-PPy-C-mixed solution was filtered, washed with warm water, and vacuum dried at 90° C. Thus, a dry powder of a cobalt supported PPy-C (support concentration of cobalt: 10 mass %) having cobalt supported on PPy-C was obtained.
