Ultra-small cuprous oxide (<10 nm) was deposited on the exterior face of alpha-zirconium phosphate (ɑ-ZrP). These nanoparticles have been successfully synthesized using ethylene diamine tetra acetic acid (EDTA) and ɑ-ZrP sheets as a chelating agent and template, respectively. In this article, nanosized cuprous oxide (CuO) loaded on the exterior face of ɑ-ZrP (CuO@ZrP) was prepared via a simple and convenient method. The coordination effect of EDTA stabilized the copper ions in solution and prevented agglomeration of CuO seed crystals into larger-sized particles. Moreover, the ɑ-ZrP sheets simultaneously acted as a template to further inhibit the growth of CuO grains. The CuO nanoparticles with the particle size of about 4 nm were uniformly loaded on the ZrP nanosheet. Furthermore, the antibacterial properties of CuO@ZrP hybrid materials and PET/CuO@ZrP antibacterial fabric were studied against E. coli (ATCC 25922) and S. aureus (ATCC 6538) by counting the number of surviving colonies. Ultra-small CuO of the CuO@ZrP composites lead to excellent antibacterial activity. It demonstrated that CuO@ZrP hybrid materials show great promise as antibacterial material widely used in various fields.
超小的氧化亚铜（<10nm）被沉积在α-磷酸锆（α-ZrP）的外表面上。这些纳米颗粒是使用乙二胺四乙酸（EDTA）和α-ZrP 片分别作为螯合剂和模板成功合成的。在本文中，通过一种简单方便的方法制备了负载在α-ZrP 外表面的纳米氧化亚铜（CuO@ZrP）。EDTA 的配位作用稳定了溶液中的铜离子，防止 CuO 晶种聚集成更大尺寸的颗粒。此外，α-ZrP 片同时充当模板，进一步抑制 CuO 晶粒的生长。CuO 纳米颗粒的粒径约为 4nm，均匀地负载在 ZrP 纳米片上。此外，通过计数存活菌落的数量，研究了 CuO@ZrP 复合材料和 PET/CuO@ZrP 抗菌织物对大肠杆菌（ATCC 25922）和金黄色葡萄球菌（ATCC 6538）的抗菌性能。CuO@ZrP 复合材料中超小的 CuO 表现出优异的抗菌活性。这表明 CuO@ZrP 复合材料作为抗菌材料具有广阔的应用前景，可广泛应用于各个领域。
