“…Material scientists have devoted their efforts to improve the photocatalytic activity of g-C 3 N 4 under visible light irradiation by coupling g-C 3 N 4 with other materials, in that the planer conjugation structure of g-C 3 N 4 can furnish a scaffold to anchor various substrates [26]. A large number of C 3 N 4 -based composite photocatalysts such as C 3 N 4 -TiO 2 [28], C 3 N 4 -SnS 2 [25], Co 3 O 4 -g-C 3 N 4 [23], C 3 N 4 -Bi 2 WO 6 [29] and C 3 N 4 -SrTiO 3 [30], etc have thence been synthesized. These works demonstrated the significantly enhanced photocatalytic activity of the g-C 3 N 4 by forming composite structures.…”

To study the photocatalytic efficiency of wastewater treatment processes, the nanocomposites of conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) and ZnO nanoparticles were prepared by in-situ synthesis. ZnO is an excellent photocatalyst under UV light, but due to high band gap, photons of visible light have insufficient energy to excite electrons from valence to conductive band, which limits its activity under visible light and therefore practical usage is limited. The PEDOT conductive polymer was used to increase the photocatalytic activity of ZnO since conductive polymers are known as efficient electron donor and good electron transporters upon visible-light excitation. Polymerization of pure PEDOT and PEDOT/ZnO nanocomposites was carried out at varying monomer:oxidant ratio (1:2; 1:3; 1:5) with the ammonium persulfate (APS) used as the oxidant. Samples were characterized by FTIR spectroscopy, XRD analysis, SEM microscopy, UV-Vis spectroscopy and TG analysis. Photocatalytic activity was assessed through removal of C.I. Reactive Red 45 (RR45) azo dye under simulated Solar and UV-A irradiation. Photocatalysis was monitored by measuring discoloration of RR45 using UV/Vis spectroscopy. The results indicate that very low concentration of PEDOT conductive polymer in PEDOT/ZnO nanocomposite can significantly contribute to the efficiency of the photocatalytic process during wastewater treatment.

Graphitic g-C3N4-WO3 composite was synthesized simply by decomposing melamine in the presence of WO3 at 500 o C. The obtained material was characterized by XRD, SEM, IR and XPS. The results showed that the as-prepared composite exhibits orthorhombic WO3 phase coated by g-C3N4 and the g-C3N4 decomposed completely with N-doped WO3 remaining at elevated calcination temperatures. The photocatalytic activity of the composite was evaluated by the photodegradation of methylene blue under visible light. An enhancement in photocatalytic activity for the graphitic g-C3N4-WO3 composite compared to the conventional nitrogendoped WO3 was observed, which can be attributed to the presence of g-C3N4 in the material.
