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.

制备了具有热催化和热催化作用的催化材料，并将其用于某些反应。甲醇在空气中的光催化氧化钛（IV）氧化物在室温下产生甲酸甲酯具有高水平的选择性（91摩尔%），表明光催化氧化和酸碱催化二聚同时发生。在紫外光照射下，Pd/TiO_2催化1-丁烯快速异构化为2-丁烯，表明光生电子和空穴加速了Pd的热催化作用。
