Description
[触媒の調製]
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時間焼成して触媒を調整した。
上記の触媒材料について、EXAFS及びTEMを用いて構造解析を行った。
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。
図4に、EXAFSによる、硫黄仕込み量:20%の、Ruを含むカルコゲナイドの構造解析結果を示す。図4の結果より、Ru−Ru結合のみ見られる。図5に、EXAFSによる、硫黄仕込み量:45%の、Ruを含むカルコゲナイドの構造解析結果を示す。図5の結果より、Ru−S結合とRu−Ru結合が見られる。図6に、EXAFSによる、硫黄仕込み量:71%の、Ruを含むカルコゲナイドの構造解析結果を示す。図6の結果より、多量のRu−S結合と少量のRu−Ru結合が見られる。
