Point-of-use (POU) water treatment systems and devices play an essential role in limited access to sanitary safe water resources. The filtering materials applied in POU systems must effectively eliminate contaminants, be readily produced and stable, and avoid secondary contamination of the treated water. We report an innovative, 2D TiC/AlO/Ag/Cu nanocomposite-modified filtration material with the application potential for POU water treatment. The material is characterized by improved filtration velocity relative to an unmodified reference material, effective elimination of microorganisms, and self-disinfecting potential, which afforded the collection of 99.6% of bacteria in the filter. The effect was obtained with nanocomposite levels as low as 1%. Surface oxidation of the modified material increased its antimicrobial efficiency. No secondary release of the nanocomposites into the filtrate was observed and confirmed the stability of the material and its suitability for practical application in water treatment.
使用点（POU）水处理系统和设备在获得卫生安全水资源受限的情况下发挥着至关重要的作用。POU系统中使用的过滤材料必须有效去除污染物，易于生产且稳定，并避免对处理后的水造成二次污染。我们报告了一种创新的二维TiC/AlO/Ag/Cu纳米复合改性过滤材料，具有用于POU水处理的应用潜力。该材料的特点是相对于未改性的参考材料，过滤速度提高，能有效去除微生物，具有自消毒潜力，在过滤器中可收集99.6%的细菌。纳米复合材料含量低至1%时即可获得此效果。改性材料的表面氧化提高了其抗菌效率。未观察到纳米复合材料向滤液中的二次释放，证实了该材料的稳定性及其在水处理实际应用中的适用性。
