Abstract Unique and controllable well-organized ZnO hollow cages were formed for the first time by smart assembly using novel combination of L-TA and EA, which can produce a strong synergistic effect in hydrothermal process. Meanwhile, the conformation of L-TA and D-TA shows that these ZnO cages have special spatial assembly order. The photocatalytic activity of Ag/ZnO is remarkably larger than that of pristine ZnO (S2) under UV or simulated sunlight irradiation. The MB rate constant k values of Ag/ZnO composites are larger than those of P25 under UV light illumination. Under simulated sunlight irradiation, S2-10% Ag/ZnO degrades 80% of RhB in 135 min. The PL, photocurrent and EIS results indicate enhanced photocatalytic performance due to the interfacial formation between Ag and ZnO, which facilitates the separation and transfer of photoinduced carriers and enhances the photocatalytic activity of Ag/ZnO composites. This work provided a new way to design and construct well-organized ZnO hollow cages and their derived Ag/ZnO photocatalysts.

ZnO空心笼及其衍生的具有增强光催化性能的Ag/ZnO复合材料的有序组装

摘要 利用L-TA和EA的新型组合，首次通过智能组装形成了独特且可控的有序ZnO空心笼，在水热过程中可以产生很强的协同作用。同时，L-TA和D-TA的构象表明这些ZnO笼具有特殊的空间组装顺序。在紫外线或模拟阳光照射下，Ag/ZnO 的光催化活性明显高于原始 ZnO（S2）。在紫外光照射下，Ag/ZnO 复合材料的 MB 速率常数 k 值大于 P25。在模拟的阳光照射下，S2-10% Ag/ZnO 在 135 分钟内降解 80% 的 RhB。PL、光电流和 EIS 结果表明，由于 Ag 和 ZnO 之间的界面形成，光催化性能增强，这有利于光致载流子的分离和转移，提高了 Ag/ZnO 复合材料的光催化活性。这项工作为设计和构建组织良好的 ZnO 空心笼及其衍生的 Ag/ZnO 光催化剂提供了一种新方法。
