“…The main peak for pristine g-C 3 N 4 powder is at 807 cm À1 , which is attributed to repeating triazine units. 45,46 Some other absorption peaks of g-C 3 N 4 also observed in FTIR are at 1200, and 1637 cm À1 , which are representatives of C N and C N functionalities, respectively. 47,48 For pristine PVDF, the main peak at 1413 cm À1 is attributed to the stretching vibrations of C H. The peaks of g-C 3 N 4 /PVDF composite membranes at 1637 cm À1 can be related to the C N stretching vibrational modes of g-C 3 N 4 .…”

Membranes combined with nanoparticles are an excellent combination capable of successfully removing various contaminants, such as dyes from wastewater while using very little energy and decreasing pollution. The present study reports an efficient approach for Remazol Black 5 (RB5) dye removal using composite graphitic carbon nitride nanosheets (g‐C3N4), polysulfone (PSF), and polyvinylidene fluoride (PVDF) membranes. The membranes were prepared using the phase inversion method, with varying quantities of g‐C3N4 nanosheets ranging from 0.1%, 0.2% to 0.3%. The prepared g‐C3N4 nanosheets were characterized by FTIR, SEM analyses, and zeta potential measurements. FTIR and SEM studies, contact angle, water permeability, COD, and dye rejection measurements were used to characterize the g‐C3N4 nanosheets embedded in PSF and PVDF membranes. After the addition of 0.3 wt% g‐C3N4, the water flux of the 0.3 wt% g‐C3N4 embedded PSF membrane was the highest, whereas the water flux of the 0.3 wt% g‐C3N4 embedded PVDF membrane was the lowest. The ultrafiltration (UF) membrane's performance with g‐C3N4 embedded showed an RB5 rejection rate of more than 80% and a COD removal efficiency of more than 45%. The results of the experimental filtration showed that RB5 rejection reached maximum values of 91.3% for 0.1 wt% g‐C3N4/PSF, and 85.6% for 0.3 wt% g‐C3N4/PVDF.

“…In such systems, the light can lead to a local electromagnetic field by generating localized surface plasmon resonance (LSPR) and hot carriers. The hot carriers move to conductive and valance bands and this phenomenon is called the LSPR sensitization [409,410]. The hot carriers can be useful for direct oxidation or reduction of chemical species.…”

g-C3N4 has drawn lots of attention due to its photocatalytic activity, low-cost and facile synthesis, and interesting layered structure. However, to improve some of the properties of g-C3N4, such as photochemical stability, electrical band structure, and to decrease charge recombination rate, and towards effective light-harvesting, g-C3N4–metal oxide-based heterojunctions have been introduced. In this review, we initially discussed the preparation, modification, and physical properties of the g-C3N4 and then, we discussed the combination of g-C3N4 with various metal oxides such as TiO2, ZnO, FeO, Fe2O3, Fe3O4, WO3, SnO, SnO2, etc. We summarized some of their characteristic properties of these heterojunctions, their optical features, photocatalytic performance, and electrical band edge positions. This review covers recent advances, including applications in water splitting, CO2 reduction, and photodegradation of organic pollutants, sensors, bacterial disinfection, and supercapacitors. We show that metal oxides can improve the efficiency of the bare g-C3N4 to make the composites suitable for a wide range of applications. Finally, this review provides some perspectives, limitations, and challenges in investigation of g-C3N4–metal-oxide-based heterojunctions.

“…10,11 However, application of pure C3N4 in photocatalysis is limited by low mobility and fast recombination of charge carriers and low absorption in visible region. 12,13,14,15 By this reason, C3N4 is usually applied in the composite materials containing versatile co-catalysts, including metallic nanoparticles, 16 metal oxides, 17 sulfides, 18 or ferrites. 19 Molybdenum sulfide MoS2 was previously studied as a co-catalyst for C3N4 in the photocatalytic reactions.…”
