Outline of Final Research Achievements

Perovskite-type oxide catalysts prepared by utilizing solid-solid transformation were applied to several heterogeneous catalytic reactions including liquid-solid and solid-solid catalytic reaction. Perovskite-type oxide exhibited the catalytic activity for cyanosilylation and Knoevenagel condensation reactions (Liquid-Solid catalytic system), suggesting the formation of both Bronsted acid and base on surface. It was found that the catalytic activity of the particulate matter (PM) oxidation over Ag-loaded perovskite-type oxide (Solid-Solid catalytic system) was comparable to that over Ag-loaded cerium dioxide which has been well-known to be the best candidate for PM oxidation. In addition, the novel preparation route of partially-substituted perovskite-type oxide was developed.
