The CeMn_xO_y/OMS-2 nanocomposites were prepared by depositing different amounts of amorphous CeMn_xO_y on the pure OMS-2 sample by the hydrothermal redox reaction of Ce(NO₃)₃ and KMnO₄. The formation of the CeMn_xO_y/OMS-2 nanocomposites causes a significant enhancement in the photothermocatalytic activity of OMS-2 for the gas-phase oxidation of benzene under the UV–vis-infrared illumination from a Xe lamp. The optimum CeMn_xO_y/OMS-2-5.0% nanocomposite exhibits very effective photothermocatalytic activity and very good durability under the UV–vis-infrared illumination. It also exhibits effective photothermocatalytic activity under the visible-infrared and infrared illumination. The significantly enhanced photothermocatalytic activity of the CeMn_xO_y/OMS-2-5.0% nanocomposite as compared to the pure OMS-2 sample is attributed to the much higher thermocatalytic activity of the former than the latter due to a significant improvement in the reducibility upon the formation of the CeMn_xO_y/OMS-2-5.0% nanocomposite. A novel photoactivation quite unlike the photocatalysis on the semiconductor photocatalyst such as anatase TiO₂ is found to obviously promote the solar-light-driven thermocatalytic activity.

CeMn _x O _y / OMS-2纳米复合材料是通过Ce（NO ₃）₃和KMnO ₄的水热氧化还原反应在纯OMS-2样品上沉积不同量的无定形CeMn _x O _y制备的。CeMn _x O _y / OMS-2纳米复合材料的形成显着增强了OMS-2在Xe灯的紫外线-可见光照射下对苯的气相氧化的光热催化活性。最佳CeMn _x O _y/OMS-2-5.0%纳米复合材料在紫外可见光照射下表现出非常有效的光热催化活性和极好的耐久性。在可见红外和红外照明下，它还表现出有效的光热催化活性。与纯OMS-2样品相比，CeMn _x O _y /OMS-2-5.0%纳米复合材料的光热催化活性显着增强，这归因于前者比后者具有更高的热催化活性，这是由于可还原性的显着提高在形成CeMn _x O _y /OMS-2-5.0%纳米复合材料时。一种新型的光活化作用，完全不同于对半导体光催化剂（如锐钛矿型TiO _2）的光催化作用 被发现明显促进了太阳光驱动的热催化活性。
