    • A carrier supporting titania thereon is further caused to carry a metal compound thereon. This metal compound is hydrogen reduced in a heating atmosphere at a first treatment temperature, then oxidized in a heating atmosphere at a second treatment temperature not higher than the first treatment temperature to thereby obtain a photocatalyst. In this event, metal is released from an extremely strong reduction state and thus highly dispersed on the catalyst in the form of fine particles so that high activity of the catalyst can be obtained. Then, by purifying gas while feeding light and heat to the photocatalyst by, for example, blacklights, a volatile organic compound such as acetaldehyde can be decomposed at a high decomposition rate through cooperation between photocatalytic activity and thermal catalytic activity of the photocatalyst.
    • 载体上的二氧化钛载体进一步在其上携带金属化合物。 该金属化合物在第一处理温度下在加热气氛中氢还原,然后在不高于第一处理温度的第二处理温度下在加热气氛中氧化,从而获得光催化剂。 在这种情况下,金属从非常强的还原状态释放,因此以细颗粒的形式高度分散在催化剂上,从而可以获得高活性的催化剂。 然后,通过例如通过黑灯对光催化剂供给光进行净化,并且通过光催化活性和光催化剂的热催化活性之间的协调可以以高分解速率分解挥发性有机化合物如乙醛。

    • A method of preparing semiconductor nano crystal anatase TiO2 solution uses titanium alkoxide Ti(OR)4 as a main component in combination with chelating agents in aqueous solution. A fluorescent lamp tube is coated with the semiconductor nano crystal anatase TiO2 solution to form a photocatalytic coating fluorescent lamp capable of cleaning air. Then a baking step is carried out at a low temperature about 100-250null C. By doped anatase TiO2 with small amount about 0-1.0 wt % of precious metals complex or transition metals oxides as nano-particle on or in the anatase TiO2 nano-particle surface, the visible light photocatalysis efficiency is increased for air cleaning. By doped with small amount Eunull3 or rare earth metal ion on or in the anatase TiO2 nano-particle surface, which is a photocatalytic material acting as fluorescent agent, the fluorescent lamp has increasing brightness of when it is turned on.
    • 制备半导体纳米晶锐钛矿TiO2溶液的方法使用钛醇钛(OR)4作为主要成分与螯合剂在水溶液中的组合。 荧光灯管涂有半导体纳米晶锐钛矿TiO2溶液,形成能够清洁空气的光催化涂层荧光灯。 然后在约100-250℃的低温下进行烘烤步骤。通过掺杂锐钛矿TiO 2,其中少量约0-1.0重量%的贵金属络合物或过渡金属氧化物作为纳米颗粒在锐钛矿TiO 2纳米颗粒上或其中 - 颗粒表面,空气净化的可见光光催化效率提高。 通过在作为荧光剂的光催化材料的锐钛型TiO 2纳米颗粒表面上或其上掺杂少量的Eu 3+或稀土金属离子,荧光灯在开启时具有增加的亮度。
