Outline of Final Research Achievements

Novel porous crystalline solid was synthesized by using ε-Keggin Mo-POM as synthetic unit. Resulting materials showed selective oxidation catalysis property and molecular oxygen activation on the basis of the elemental diversity, structural diversity, and redox dynamism.
Novel porous crystalline solid was synthesized by assembling metal oxide nano-wire formed with 1D chaining of 6-membered ring units. The material showed unique selective oxidation performance due to the electron transfer through the 1D chain. Novel porous crystalline solid was synthesized through unit synthesis of cuban-type unit of W oxides and V-linkers. The crystalline materials formed micro-channels and cages and therefore became one with high elemental exposure state. It was found that the materials showed extremely catalytically active for de-NOx reaction superior to existing catalysts.
