Outline of Final Research Achievements

We have developed high performance cobalt oxide catalysts for oxidative decomposition of ammonia in waste water under mild reaction conditions. Catalytic performances of the cobalt oxide catalysts changed depending on their particle configuration and cubic and truncated octahedron shaped cobalt oxides gave high catalytic activity for the reaction. Thermal treatment of cobalt oxides in waste water containing ammonia brought about formation of amino group on the surface. leading to enhancement in the catalytic performance with repeated use for the reaction.
