In recent years, polymer nanocomposites (PNCs) have attracted the attention of scientists and techno logists in water purification due to improved processability, surface area, stability, tunable properties, and cost effectiveness. PNCs showed fast deco ntamination ability with high sele ctivity to remove various pollutants. This review provides uptodate information about the importance of PNCs in the removal of metal ions, dyes, and micro organism from polluted water. The general methodology for preparation and properties of nanocomposites with reference to PNCs is given. Different adsorption isotherm and kinetic models along with thermodynamic parameters for adsorption have been discussed.

“…To enhance the separation of photogenerated charges and improve the efficiency of the photocatalytic process, heterojunction composites or multilayered structures have been introduced, including doping and coupling g-C 3 N 4 with metal, nonmetal and other semiconductor materials, such as Ag/g-C 3 N 4 [7], CdS/g-C 3 N 4 [8], ZnO/g-C 3 N 4 [9], AuPd/g-C 3 N 4 [10], and WO 3 /g-C 3 N 4 [11]. In the last case, the composite heterostructure presents a much higher photocatalytic activity than the pristine g-C 3 N 4 and WO 3 components [12][13][14]. Moreover, recent investigations in the field of photocatalysis attempt to explore novel trends and present perspectives of innovative nanostructured photocatalysts inside and outside the well-established frame of advanced oxidation processes (AOPs).…”

A bifunctional thin film photocatalyst consisting of graphitic carbon nitride on tungsten trioxide (g-C3N4/WO3) is introduced for the improvement of photocatalytic activity concerning hexavalent chromium reduction and methylene blue dye removal in water, compared to the bare, widely used WO3 semiconductor. A bilayered structure was formed, which is important for the enhancement of the charge carriers’ separation. The characterization of morphological, structural, optoelectronic, and vibrational properties of the photocatalysts permitted a better understanding of their photocatalytic activity for both dye degradation and Cr+6 elimination in water and the analysis of the photocatalytic kinetics permitted the determination of the corresponding pseudo-first-order reaction constants (k). Trapping experiments performed under UV illumination revealed that the main active species for the photocatalytic reduction of Cr+6 ions are electrons, whereas in the case of methylene blue azo-dye (MB) oxidation, the activation of the corresponding photocatalytic degradation comes via both holes and superoxide radicals.

“…Therefore, g-C 3 N 4 is widely used to couple with other semiconductor photocatalysts for enhancement of their photocatalytic activity, such as, TiO 2 , SiO 2 , ZnO, Al 2 O 3 , WO 3 , BiVO 4 , Ag 2 CO 3 , Ag 3 VO 4 , Bi 2 MoO 6 , In 2 O 3 and so on. [21][22][23][24][25][26][27][28][29][30] Currently, a few studies have been focused on combining g-C 3 N 4 with Ag 3 PO 4 . Zhang et al 31 used the ionimpregnating method to synthesis graphitic carbon nitride/ silver phosphate (g-C 3 N 4 /Ag 3 PO 4 ) bulk heterojunction, and it showed enhanced photocatalytic activity for decolorization of RhB.…”
