Abstract
As a promising organic semiconducting material, polymeric graphitic carbon nitride (g-C3N4) has attracted much attention due to its excellent optical and photoelectrochemical properties, thermal stability, chemical inertness, nontoxicity, abundance, and low cost. Its advantageous visible light-induced photocatalytic activity has already been beneficially used in the fields of environmental remediation, biological applications, healthcare, energy conversion and storage, and fuel production. Despite the recognized potential of g-C3N4, there is still a knowledge gap in the application of g-C3N4 in the field of textiles, with no published reviews on the g-C3N4-functionalization of textile materials. Therefore, this review article aims to provide a critical overview of recent advances in the surface and bulk modification of textile fibres by g-C3N4 and its composites to tailor photocatalytic self-cleaning, antibacterial, and flame retardant properties as well as to create a textile catalytic platform for water disinfection, the removal of various organic pollutants from water, and selective organic transformations. This paper highlights the possibilities of producing g-C3N4-functionalized textile substrates and suggests some future prospects for this research area.

Increased awareness of the importance of sustainable development and environmentally friendly approaches in various technological fields, including chemical textile finishing, has dictated the introduction of “green” finishing agents and non-hazardous protocols for the chemical modification of textile substrates
In contrast to graphene and carbon nanotubes, graphitic carbon nitride (g-C3 N4 ), which belongs to the group of carbon-based nanomaterials, seems to be virtually unexplored in textile applications (Figure 1)
