Outline of Final Research Achievements

Niobium oxide composed of nano-plate particles with the width of 35 nm and the length of 200 nm can be readily synthesized from the nanocrystalline niobium compound intercalating ethylene glycol obtained by the solvothermal reaction of niobium ethoxide in ethylene glycol. The solvothermally-synthesized catalysts showed much higher activities for selective photooxidation of benzyl alcohol to benzaldehyde under visible light irradiation than commercial niobium oxide. Photooxidation of hydrocarbons under visible light hardly proceeds over niobium oxide, but the niobium oxide heat-treated under a vacuum condition is found to show a catalytic activity for photooxidation of cyclohexene under visible light.
