“…To date, g-C 3 N 4 has been applied to cotton [ 40 , 41 , 42 , 43 , 44 , 45 , 46 ], polyacrylonitrile [ 47 , 48 , 49 , 50 ], polyester and polyester/viscose fibres [ 51 , 52 , 53 , 54 ], polyethylene terephthalate [ 55 , 56 ], and polylactic acid [ 57 ]. Information about g-C 3 N 4 precursors, g-C 3 N 4 modification, the application method, and the performance of the textile surface functionalized by g-C 3 N 4 is summarised in Table 1 .…”

“…Prior to textile application, the ex-situ synthesis of g-C 3 N 4 was conducted by thermal condensation of dicyandiamide, melamine, or urea precursors heated to 450 °C, 500 °C, or 550 °C and calcined from 2 to 5 h. Subsequently, the synthesised g-C 3 N 4 was cooled to room temperature and ground into a powder. To prepare g-C 3 N 4 nanosheets, exfoliation was conducted in water [ 46 , 53 ], H 2 SO 4 [ 42 ] or in NaOH [ 44 ] under ultrasonic treatment. In addition to the unmodified material, the oxidised form of g-C 3 N 4 [ 41 ], carboxyl-modified and carboxyl-3-triethoxysilylpropylamine-modified g-C 3 N 4 [ 45 ] have also been used for textiles.…”

“…To produce functional properties, both the surface and bulk chemical modifications of the textile substrates were conducted. For the surface modification, g-C 3 N 4 was applied using the conventional pad–dry–cure technique [ 53 ], double-dip-double-nip padding, or immersion in the g-C 3 N 4 suspension under suitable conditions followed by squeezing and drying with or without curing [ 40 , 41 , 43 , 45 , 51 , 54 ], spraying [ 44 ] as well as a layer-by-layer (LbL) self-assembly technique [ 42 , 46 ]. Electrospinning was used for fibre bulk modification [ 47 , 48 , 49 , 50 , 55 , 56 , 57 ].…”

Graphitic Carbon Nitride as a New Sustainable Photocatalyst for Textile Functionalization

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.

Flexible TiO2/PVDF/g-C3N4 Nanocomposite with Excellent Light Photocatalytic Performance

et al. 2019

As the world faces water shortage and pollution crises, the development of novel visible light photocatalysts to purify water resources is urgently needed. Over the past decades, most of the reported photocatalysts have been in powder or granular forms, creating separation and recycling difficulties. To overcome these challenges, a flexible and recyclable heterostructured TiO2/polyvinylidene fluoride/graphitic carbon nitride (TiO2/PVDF/g-C3N4) composite was developed by combining electrospinning, sintering and hydrothermal methods. In the composite, PVDF was used as a support template for removing and separating the photocatalyst from solution. Compared with pure TiO2, the TiO2/PVDF/g-C3N4 composite exhibited the extended light capture range of TiO2 into the visible light region. The photogenerated carriers were efficiently transferred and separated at the contact interface between TiO2 and g-C3N4 under visible light irradiation, which consequently increased the photocatalytic activity of the photocatalyst. In addition, the flexible composites exhibited excellent self-cleaning properties, and the dye on the photocatalysts was completely degraded by the as-prepared materials. Based on the intrinsic low cost, recyclability, absorption of visible light, facile synthesis, self-cleaning properties and good photocatalytic performances of the composite, the photocatalyst is expected to be used for water treatment.
