The drinking water shortage is globe concern currently, thus, developing an economical, green, antibacterial composites is urgent. Here, we report a simple and scalable strategy to synthesize zeolite-cellulose composites by the filter paper immersed in the precursor solution of synthetic zeolite. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence spectrophotometer (XRF), infrared spectra (IR), and thermogravimetry analyzer (TGA). It was confirmed that the sub-micron zeolite was successfully embedded into cellulose. Zn²⁺ and Cu²⁺ are induced into the composites by ion exchange, the composites were able to able to kill nearly all viable bacteria of 1 L of the natural water sample via gravity driving, demonstrating high suitability for practical water disinfection. Furthermore, after the dynamic test of deionized water, the contents of Zn²⁺ and Cu²⁺ ions exuded are far below the standard of drinking water, indicating that the materials are safe and have a long-term antibacterial property.

饮用水短缺是当前全球关注的问题，因此，开发一种经济、绿色、抗菌的复合材料迫在眉睫。在这里，我们报告了一种简单且可扩展的策略，通过将滤纸浸入合成沸石的前体溶液中来合成沸石-纤维素复合材料。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、X射线荧光分光光度计（XRF）、红外光谱（IR）和热重分析仪（TGA）对样品进行表征。证实亚微米沸石成功嵌入纤维素中。Zn ²⁺和 Cu ²⁺通过离子交换诱导复合材料，复合材料能够通过重力驱动杀死 1 L 天然水样中的几乎所有活细菌，证明其非常适用于实际水消毒。此外，经过去离子水动态测试，渗出的Zn ²⁺和Cu ²⁺离子含量远低于饮用水标准，表明该材料安全且具有长期抗菌性能。
