Emerging and Promising Multifunctional Nanomaterial for Textile Application Based on Graphitic Carbon Nitride Heterostructure Nanocomposites.

Nanocomposites constructed with heterostructures of graphitic carbon nitride (g-C 3 N 4 ), silver (Ag), and titanium dioxide (TiO 2 ) have emerged as promising nanomaterials for various environmental, energy, and clinical applications. In the field of textiles, Ag and TiO 2 are already recognized as essential nanomaterials for the chemical surface and bulk modification of various textile materials, but the application of composites with g-C 3 N 4 as a green and visible-light-active photocatalyst has not yet been fully established. This review provides an overview of the construction of Ag/g-C 3 N 4 , TiO 2 /g-C 3 N 4 , and Ag/TiO 2 /g-C 3 N 4 heterostructures; the mechanisms of their photocatalytic activity; and the application of photocatalytic textile platforms in the photochemical activation of organic synthesis, energy generation, and the removal of various organic pollutants from water. Future prospects for the functionalization of textiles using g-C 3 N 4 -containing heterostructures with Ag and TiO 2 are highlighted.
