In this paper, a simple and effective method to prepare Ag-Ce/ZnO nanorods photocatalyst and grow them controllably on modified polyester fabrics was presented to fabricate multifunctional textiles. Analytical grade zinc acetate dihydrate and sodium hydroxide were used as the main raw materials to prepare Ag-Ce/ZnO nanorods. Morphological, structural and chemical characterization of the Ag-Ce/ZnO nanorods was performed by XRD, UV-vis and other spectroscopies. The results showed that the Ag-Ce/ZnO nanorods had a hexagonal wurtzite structure. After 60 minutes of irradiation under ultraviolet light, the Ag-Ce/ZnO nanorods showed a percentage photodegradation of 93.14% for a methylene blue (MB) solution. Modified polyester fabrics covered with the Ag-Ce/ZnO nanorods were then prepared in a water bath. By a series of tests, it was observed that the Ag-Ce/ZnO nanorods on the modified polyester surface were neatly arranged and had good photocatalytic properties. Moreover, the UPF of the modified polyester fabric after finishing increased from 30.4 to 877.2. The multifunctional properties of the finished fabric exhibited good durability.
本文提出了一种简单有效的方法来制备 Ag-Ce/ZnO 纳米棒光催化剂，并将其可控地生长在改性聚酯织物上，以制备多功能纺织品。使用分析纯的三水合醋酸锌和氢氧化钠作为主要原料来制备 Ag-Ce/ZnO 纳米棒。通过 XRD、UV-vis 等光谱对 Ag-Ce/ZnO 纳米棒的形貌、结构和化学性质进行了表征。结果表明，Ag-Ce/ZnO 纳米棒具有六方纤锌矿结构。在紫外光照射 60 分钟后，Ag-Ce/ZnO 纳米棒对亚甲基蓝（MB）溶液的光降解率达到 93.14%。然后在水浴中制备了覆盖有 Ag-Ce/ZnO 纳米棒的改性聚酯织物。通过一系列测试，观察到 Ag-Ce/ZnO 纳米棒在改性聚酯表面整齐排列，具有良好的光催化性能。此外，整理后改性聚酯织物的 UPF 值从 30.4 增加到 877.2。整理后的织物表现出良好的多功能耐久性。
