Photocatalytic optical fibers are promising materials for degrading organic pollutants in wastewater, owing to their low light mass transfer resistance, their high efficiency of light utilization, and their inhibition of photocatalyst deactivation. In particular, optical fibers have been applied for the removal of phenols, dyes, organic acids and antibiotics in wastewater. Yet, optical fibers have limitations such as poor photocatalytic activity and low sustainability. Here, we review the principle and use of photocatalytic optical fibers, including photocatalytic quartz and plastic optical fibers, for the degradation of the organic pollutants in water. We present methods to enhance photocatalytic activity, light utilization efficiency, and adhesion strength by using TiO₂-based photocatalytic coatings.

光催化光纤由于其低的光传质阻力，高的光利用效率以及对光催化剂失活的抑制作用，是用于降解废水中有机污染物的有前途的材料。特别是，光纤已用于去除废水中的苯酚，染料，有机酸和抗生素。但是，光纤具有局限性，例如光催化活性差和可持续性低。在这里，我们回顾光催化光纤的原理和用途，包括光催化石英和塑料光纤，以降解水中的有机污染物。我们提出了通过使用基于TiO ₂的光催化涂层来增强光催化活性，光利用效率和粘附强度的方法。
