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

Nanocomposites constructed with heterostructures of graphitic carbon nitride (g-C₃N₄), silver (Ag), and titanium dioxide (TiO₂) have emerged as promising nanomaterials for various environmental, energy, and clinical applications. In the field of textiles, Ag and TiO₂ are already recognized as essential nanomaterials for the chemical surface and bulk modification of various textile materials, but the application of composites with g-C₃N₄ 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-C₃N₄, TiO₂/g-C₃N₄, and Ag/TiO₂/g-C₃N₄ 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-C₃N₄-containing heterostructures with Ag and TiO₂ are highlighted.
