In this paper, we report an antibacterial, recyclable nanocellulose-titanium dioxide/polyester nonwoven fabric (NC-TiO/PET) composite for the highly efficient photocatalytic degradation of dyes. The NC-TiO was loaded onto the surface of flexible PET nonwoven fabric through a simple swelling and dipping method. The NC-TiO in the particle size range of ~10 nm were uniformly attached to the surface of the PET fibers. The NC-TiO/PET composite has the ability to achieve the stable photocatalytic degradation of dyes and presents antibacterial properties. The degradation rates to methylene blue (MB) and acid red (AR) of the NC-TiO/PET composite reached 90.02% and 91.14%, respectively, and the inhibition rate of was >95%. After several rounds of cyclic testing, the photocatalytic performance, antibacterial performance, and mechanical stability of the NC-TiO/PET composite remained robust.

在本文中，我们报道了一种用于高效光催化降解染料的抗菌、可回收的纳米纤维素 - 二氧化钛/聚酯无纺布（NC-TiO/PET）复合材料。通过简单的溶胀和浸渍方法将NC-TiO负载到柔性PET无纺布表面。粒径在~10 nm范围内的NC-TiO均匀地附着在PET纤维表面。NC-TiO/PET复合材料具有实现染料稳定光催化降解的能力，并呈现出抗菌性能。NC-TiO/PET复合材料对亚甲基蓝（MB）和酸性红（AR）的降解率分别达到90.02%和91.14%，对大肠杆菌的抑制率>95%。经过几轮循环测试后，NC-TiO/PET复合材料的光催化性能、抗菌性能和机械稳定性仍然很强。
