Outline of Final Research Achievements

The apatite-type phosphates containing Cu in the channel were prepared and the catalytic performance of the Cu-containing apatite supported metal catalysts was investigated. Cu ion was introduced by loading of a Cu aqueous solution on a hydroxyapatite and post-annealing. Reversible incorporation/deposition of Cu into the channel site was found. The introduction of Cu improved the catalytic activity for reduction of NOx at low temperature.
