Preparation of (Nitrogen Compound and Cobalt Compound)-Added Polyacrylonitrile-Polymethacrylic Acid Copolymer (PAN-Co-PMA)

[0142]1.5 g of polyacrylonitrile-polymethacrylic acid copolymer (referred to as “PAN-co-PMA” hereinafter) was dissolved in 20 g of dimethylformamide. Thereafter, 1.5 g of cobalt chloride hexahydrate and 1.5 g of 2-methylimidazole were added, and agitation was performed for 2 hours to obtain a blue solution.

[0143]Next, the blue solution was vacuum-dried at a temperature of 60° C. to obtain a (nitrogen compound and cobalt compound)-added PAN-co-PMA. [Infusibilization Treatment]

[0144]Next, an infusibilization treatment was performed.

[0145]First, the obtained (nitrogen compound and cobalt compound)-added PAN-co-PMA was set into a forced circulation-type dryer.

[0146]Further, under air atmosphere, the temperature was raised from room temperature to 150° C. over 30 minutes, then raised from 150 to 220° C. over 2 hours, and then the temperature was held at 220° C. for 3 hou

[0156]1.5 g of PAN-co-PMA was dissolved in 20 g of dimethylformamide. Thereafter, 0.75 g of cobalt chloride hexahydrate and 0.75 g of 2-methylimidazole were added, and agitation was performed for 2 hours to obtain a blue solution.

[0157]Next, the blue solution was vacuum-dried at a temperature of 60° C. to obtain a (nitrogen compound and cobalt compound)-added PAN-co-PMA.

[0158]The infusibilization treatment and the steps after the infusibilization treatment described in Example 1 were also performed on the obtained (nitrogen compound and cobalt compound)-added PAN-co-PMA to obtain a carbon catalyst, which was used as a specimen of Example 2.

[0159]1.5 g of PAN-co-PMA was dissolved in 20 g of dimethylformamide. Thereafter, 1.5 g of cobalt chloride hexahydrate and 0.75 g of 2-methylimidazole were added, and agitation was performed for 2 hours to obtain a blue solution.

[0160]Next, the blue solution was vacuum-dried at a temperature of 60° C. to obtain a (nitrogen compound and cobalt compound)-added PAN-co-PMA.

[0161]The infusibilization treatment and the steps after the infusibilization treatment described in Example 1 were also performed on the obtained (nitrogen compound and cobalt compound)-added PAN-co-PMA to obtain a carbon catalyst, which was used as a specimen of Example 3.
