A novel biodegradable porous graphitic carbon nitride/poly(lactic acid) fiber photocatalyst for efficient elimination of carbamazepine under solar irradiation

Surface Physicochemistry Modification and Structural Nanoarchitectures of g‐C3N4 for Wastewater Remediation and Solar Fuel Generation

“…[210,211] Qian et al reported the presence of a highly dense macroporous structure on the surface of untreated polylactic acid (U-PLA) (see Figure 18a,b). [211] Upon addition of g-C 3 N 4 , the uneven surface was observed along with the decrease of the Figure 16. A comparative representation of porous structure.…”

Graphitic Carbon Nitride as a New Sustainable Photocatalyst for Textile Functionalization

“…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 .…”

“…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 ].…”

“…Among the prominent textile functional properties produced by g-C 3 N 4 are the photocatalytic self-cleaning of various stains [ 43 , 44 ]; the degradation of dyes [ 40 , 42 , 43 , 44 , 50 ]; water disinfection and antibacterial properties [ 40 , 45 , 47 ]; the degradation of antibiotics, bactericides, and insecticides [ 42 , 51 , 53 , 54 , 55 , 56 , 57 ]; the purification of oilfield produced water [ 49 ]; the sensing and photocatalytic detoxification of air pollutants [ 41 , 42 , 44 ]; and thermal stability and flame retardancy [ 46 ]. In addition to textile functionalities, the recyclability and stability of the g-C 3 N 4 modified textile substrates have also been investigated [ 43 , 47 , 51 , 53 ]…”

“…g-C 3 N 4 nanosheets were also incorporated into the bulk of synthetic fibres, where polyacrylonitrile [ 47 , 48 , 49 , 50 ] and polyethylene terephthalate [ 55 , 56 ] as well as polylactic acid [ 57 ] were used as polymer matrices for the incorporation of g-C 3 N 4 . In these cases, g-CN was dispersed in the polymer solution and was used as a spinning solution for the production of the nonwoven fabrics.…”
