The development of innovative materials for environmental cleaning applications has been the focus of substantial research efforts due to the growing global concern over environmental pollution and the need for sustainable solutions. In light of this, textile composites based on nano photocatalysts have become an exciting new way to tackle a range of environmental issues. Nanophotocatalyst-based textile composites have a wide range of environmental uses, including materials for oil spill cleanup, water purification filters, and self-cleaning textiles and masks for air purification. These composites are appropriate for a variety of real-world situations due to their benefits of scalability, durability, and adaptability. The research status on textile composites based on nano photocatalysts and their uses in environmental remediation is described in this chapter.
