| Research Abstract |
It is clarified that mono-dispersed spherical particles consisting of sulfide and carbon are synthesized by solvothermal reactions of metal carbonyls and sulfur in alcohols. For the preparation of oxygen reduction catalysts by solvothermal reactions, the addition of carbon black to the starting materials before the reactions improved the property of the oxygen reduction catalysts. The ruthenium selenide system showed the better catalytic performance than the ruthenium sulfide system.
