Description
[触媒の調製]
カーボン担体としてKetjen Black(商標名)を用い、ルテニウムカルボニル、モリブデンカルボニル、イオウをアルゴン中で140℃で加熱し、冷却の後、アセトンで洗浄し、ろ過をする。ろ過物であるRuMoS/C(Ru:Mo:S=5:1:5、60wt%)を350℃で2時間焼成してカルコゲナイド系触媒を調整した。
上記RuMoS/C、RuS/C及びMoS/Cに対してヘリウムガス中でのMS曲線を求めた。図1は、RuMoS/CのMS曲線を示す。図1の結果より、昇温に伴う硫黄分の脱離が少ないことが分かる。図2は、RuS/CのMS曲線を示す。図2の結果より、昇温に伴う硫黄分の脱離が多いことが分かる。図3は、MoS/CのMS曲線を示す。図3の結果より、昇温に伴う硫黄分の脱離が少ないことが分かる。これらの結果より、触媒成分にMoを添加することによって硫黄分の脱離を抑制し、カルコゲナイド系触媒としての特性を発揮できることが分かる。また、RuMoS/CとRuS/Cの酸素還元電流値の比較からも、カルコゲナイド系触媒におけるMoの添加効果が分かった。
合成した上記のカルコゲナイド系触媒材料についてXANESを用いた構造解析を行った結果、カルコゲナイド系触媒には、遷移金属カルコゲナイド物と遷移金属カルコゲナイド酸物が含まれることが分かった。上記RuMoS/Cの場合は、硫化物と硫酸物が含まれる。
熱処理条件を300℃×1h、350℃×1h、500℃×1h、350℃×2hに変化させて、上記と同様にカルコゲナイド系触媒材料(全てRu:Mo:S=5:1:5)を調整した。比較のために、上記MoS/CとRuS/Cを用いた。
硫黄仕込み量を0、20、45、71mol%に変化させて、上記と同様に触媒材料を調整した。
