摘要
制作控制作文、控制拓扑学的 ZnO/TiO2 反的蛋白石(IO ) 的一个新奇方法拍摄使用一个积极牺牲的 ZnO IO 模板被开发了。这个方法包括一个二拍子的圆舞过程，由简单电气化学的免职用的 ZnO IO 的准备一自己组装由液体阶段免职(LPD ) 的 ZnO/TiO2 IO 的胶体的水晶模板和准备在房间温度处理的聚苯乙烯。ZnO/TiO2 IO 的作文和拓扑学能被改变 LPD 的持续时间容易控制。在 20 min LPD 过程以后，有非拥挤不堪的以脸为中心的立方的空气范围数组的 ZnO/TiO2 合成 IO 被获得。延长持续时间到 60 min，有显然变厚的墙的纯 TiO2 IO (TIO-LPD60 ) 被形成。为组合、拓扑的变化的形成机制被讨论。为甲又蓝色的降级的样品的紫外 photocatalytic 性质上的初步的研究表明作文和拓扑学显著地影响了 IO 电影的 photocatalytic 活动。ZnO/TiO2 合成 IO 比纯 ZnO 和纯 TiO2 IO 表明活动的更高的度，尽管他们让类似的 IO 围厚度。而且，与从 ~ 增加 IO 墙厚度 52 nm 到 ~ 90 nm， TIO-LPD60 展出 photocatalytic 性能的高水平。
A novel method to fabricate composition- （IO） films using a positive sacrificial ZnO and topology-controlled ZnO/TiO2 inverse opals IO template has been developed. This method includes a two-step process, preparation of ZnO IO by a simple electrochemical deposition using a self-assembly polystyrene colloidal crystal template and preparation of ZnO/TiO2 IO by a liquid phase deposition （LPD） process at room temperature. The composition and topology of ZnO/TiO2 IO can be easily controlled by changing the duration of the LPD. After 20 min LPD process, a ZnO/TiO2 composite IO with non-close-packed face-centered cubic air sphere array was obtained. Prolonging the duration to 60 min, a pure TiO2 IO （TIO-LPD60） with obviously thickened walls was formed. The formation mechanism for the compositional and topological variation was discussed. A preliminary study on UV photocatalytic property of the samples for degradation of methylene blue reveals that the composition and topology significantly influenced the photocatalytic activity of the IO film. The ZnO/TiO2 composite IO demonstrates a higher degree of activity than both pure ZnO and pure TiO2 IO, although they have a similar IO wall thickness. Moreover, with increasing IO wall thickness from -52 nm to -90 nm, TIO-LPD60 exhibits the highest level of photocatalytic performance.
