The removal of dyes via photocatalytic degradation has been identified as an eco-friendly method for producing clean and purified water. Natural cellulosic fibers are significant renewable resource and important in a wide range of applications. Herein, we report a natural cellulosic Juncus effusus (JE) fiber with 3D network structure as a framework to provide controllable space for the growth of TiO2 particles. The TiO2-JE showed remarkable activity in the removal of C.I. Reactive Red 120 (RR120), C.I. Direct Yellow 12 (DY12), and methylene blue (MB) with a photodegradation efficiency of 99.9 % under simulated sunlight irradiation. Additionally, an orientate fabric was fabricated using the prepared TiO2-JE fibers for the photocatalytic degradation of dye-contaminated water in the sun, further confirming its practical application. The TiO2 decorated natural cellulosic JE fiber can be a promising material for photocatalysis and sustainable chemistry.

二氧化钛装饰了天然纤维素Juncus effusus纤维，可对染料进行高效的光降解。

通过光催化降解去除染料已被确定为生产清洁和纯净水的环保方法。天然纤维素纤维是重要的可再生资源，并且在广泛的应用中很重要。在这里，我们报告了具有3D网络结构的天然纤维素Juncus effusus（JE）纤维，可为TiO2颗粒的生长提供可控的空间。TiO2-JE在去除CI活性红120（RR120），CI直接黄12（DY12）和亚甲基蓝（MB）方面表现出显着的活性，在模拟阳光照射下的光降解效率为99.9％。另外，使用所制备的TiO 2 -JE纤维制造了定向织物，用于在阳光下光催化降解染料污染的水，进一步证实了其实际应用。
