Outline of Final Research Achievements

Hydrogen is one of the most promising alternatives to coal, oil and natural gas for producing electrical energy. Significant research effort has been conducted on the synthesis and characterization of hydrogen evolution catalysts which possess the ability of electrochemical water splitting. In this study, cobalt molybdenum sulfides (Co-Mo-Sx) were prepared by a cross-linking reaction of cobalt (II) ions with tetrathiomolybdato ions and their electrochemical properties were investigated. Co-Mo-Sx electrodes exhibited good chemical stability and performance for hydrogen evolution reaction under strong base conditions.

Academic Significance and Societal Importance of the Research Achievements

化石燃料の燃焼による二酸化炭素の排出を抑制し、さらなる地球温暖化の進行を阻止するための物質探索は、社会的意義のある研究課題である。本研究において、貯蔵可能で二酸化炭素を排出しないエネルギー源である水素を水分解によって生成することが可能な非晶質カルコゲナイドの合成方法を確立し、その基礎的物性を明らかにしたことは、水分解触媒実用化への橋頭保となる学術的に意義のある研究成果であったと言える。
