| Outline of Final Research Achievements |
Expose of supported nickel catalysts to air made their catalytic activity lost in reduction of nitrate with hydrogen in water. Thus, to bring out their inherent catalytic performances, it was necessary to remove air from the reaction systems as much as possible. The catalytic performances of supported nickel catalysts for reduction of nitrate with hydrogen in water were significantly changed depending on support for nickel and co-catalyst added to nickel. It was found that a supported nickel catalyst with alumina support and zinc as a co-catalyst with 0.04 of atomic ratio of zinc to nickel showed high catalytic activity and suppressed undesirable ammonia formation.
