“…The presence of nitrogen atoms in the graphene-like layered g-C 3 N 4 structure gives g-C 3 N 4 its unique properties, such as semiconductor properties, solid alkalinity, and complexing ability, thus endowing it with better performance than graphene in some aspects [ 19 , 20 ]. g-C 3 N 4 has been extensively used as a polymeric photo-catalyst for solar hydrogen production and environmental purification, as well as oxygen reduction and evolution [ 21 , 22 , 23 ]. A few recent studies have also reported that nanostructured g-C 3 N 4 exhibits excellent gas sensing properties owing to its excellent catalytic property [ 24 , 25 ].…”

Graphitic carbon nitride (g-C3N4) nanosheets were exfoliated from bulk g-C3N4 and utilized to improve the sensing performance of a pure graphene sensor for the first time. The role of hydrochloric acid treatment on the exfoliation result was carefully examined. The exfoliated products were characterized by X-ray diffraction (XRD) patterns, scanning electron microscopy (SEM), atomic force microscopy (AFM), and UV-Vis spectroscopy. The exfoliated g-C3N4 nanosheets exhibited a uniform thickness of about 3–5 nm and a lateral size of about 1–2 µm. A g-C3N4/graphene nanocomposite was prepared via a self-assembly process and was demonstrated to be a promising sensing material for detecting nitrogen dioxide gas at room temperature. The nanocomposite sensor exhibited better recovery as well as two-times the response compared to pure graphene sensor. The detailed sensing mechanism was then proposed.

“…g-C 3 N 4 has been extensively used as a polymeric photo-catalyst for solar hydrogen production and environmental purication, as well as oxygen reduction and evolution. [13][14][15][16] However, few studies on the uorescent property of bulk g-C 3 N 4 have been reported as bulk g-C 3 N 4 can hardly form a stable suspension. Very recently, Zhang et al 17 found that g-C 3 N 4 nanosheets had a high photoluminescence performance, which opened another door for the application of g-C 3 N 4 .…”

Highly fluorescent g-C3N4 nanosheets were facilely fabricated by exfoliating bulk g-C3N4 under ultrasonic irradiation for 1 h. The atomic force microscopy (AFM) image shows that the resultant g-C3N4 nanosheets are ∼6-14 nm thick, and the suspension is stable in air for several weeks. Remarkably, the obtained nanosheets exhibited strong fluorescence with an extremely high quantum yield (QY) up to 32%, and high sensitivity, selectivity, as well as a fast response to nitro aromatic explosives were observed. Typically, the quenching efficiency coefficient Ksv for PNP was 30,460 M(-1), which proved that the resultant nanosheets possessed an extremely high sensitivity for nitro-phenol PNP detection.

“…In the prepared catalyst however, some of these absorptions are overlapped with the absorptions of g‐C 3 N 4 . Moreover, a characteristic absorption band is expected to appear at 335 nm for the coexisting NiO nanoparticles that is obscured because of the overlap with the existing absorption bands. It should also be mentioned that a sharp increase in the intensity of the absorption bands of the catalyst might be attributed to the localized surface plasmon resonance of palladium nanoparticles …”

When a single metal fails to promote an efficient Suzuki-Miyaura coupling reaction at ambient temperature, the synergistic cooperation of two distinct metals might improve the reaction. To examine the synergistic effect of palladium and nickel for catalyzing Suzuki coupling reaction, g-C 3 N 4 supported metal nanoparticles of PdO, NiO and Pd-PdO-NiO were prepared, characterized and their catalytic activities evaluated over different aryl halides at room temperature and 78°C.The morphological characterization of Pd-PdO-NiO/g-C 3 N 4 demonstrated that the bimetallic particles were uniformly dispersed over the g-C 3 N 4 layers with diameters ranging from 3.5-7.7 nm. XPS analysis showed that nanoparticles of Pd-PdO-NiO consisted of Pd(II), Pd(0) and Ni(II) sites. The experiments performed on the catalytic activity of Pd-PdO-NiO/g-C 3 N 4 showed that the prepared catalyst demonstrated an efficient activity without using toxic solvents.
