Research Abstract

Catalytic materials exhibiting photocatalysis and thermocatalysis were prepared and used for some reactions. Photocatalytic oxidation of methanol in air over titanium(IV) oxide at room temperature yielded methyl formate with a high level of selectivity (91 mol%), indicating that photocatalytic oxidation and acid-base-catalyzed dimerization occurred simultaneously. Rapid isomerization of 1-butene to 2-butenes over Pd/TiO_2 was observed under irradiation of UV light, suggesting that thermocatalysis of Pd was accelerated by photogenerated electrons and holes.
