“…In the BUChA-I/g-C 3 N 4 composite, charge transfer (+0.18) was observed from the g-C 3 N 4 to the BUChA adduct, which indicated that the former was the electron donor material [37]. The interfacial charge transfer process inhibited the charge carrier's (electron/hole) recombination on g-C 3 N 4 surface, which is beneficial for photocatalytic applications [38,[42][43][44].…”

“…Immobilization of organic molecules over g-C 3 N 4 surface facilitates the charge transfer process and inhibits the recombination process [37]. For example, introducing 11,11,12,12-tetracyanonaphtho-1,4-quinodimethane (TCNAQ) over g-C 3 N 4 surface enhanced the charge separation and induced charge carriers migration [38]. This process inhibits the charge recombination and enhances photocatalytic activity.…”

The molecular complexes between barbituric acid (BU) and chloranilic acid (ChA) over graphitic nitride (g-C3N4) are investigated. The molecular complexes and the nanocomposite were investigated both in solid state and in methanol. The solid complexes and the corresponding nanocomposite were investigated using FTIR, TGA, and UV-Vis spectroscopy. The structures were explored using DFT calculations using wB97XD/ and def2-TZVP basis set. The DFT calculations revealed the formation of hydrogen-bonded complexes, which initiate the proton transfer from ChA to BU. Immobilization of the BUChA complex over the g-C3N4 sheet was stabilized by weak non-covalent interactions, such as π–π interactions. g-C3N4 facilitated the charge transfer process, which is beneficial for different applications.

“…According to the previous studies, metalhalide perovskite QDs can be passivated by anchoring them on some two dimensional materials (e.g., Graphitic carbon nitride (g-C3N4) and graphene oxide) [10,15] , to prevent the crystal structure of the perovskite QDs from decomposition. Especially, 2D g-C3N4 nanosheets have gained special attractions owing to its suitable bandgap, high chemical stability, abundance and low cost, which makes it a potential candidate for solar energy conversion, environment purification, and bioimaging applications [16][17][18][19][20][21] . In view of the above advantages, g-C3N4 can be served as an ideal material to passivate perovskite QDs.…”

Metal-halide perovskite quantum dots (QDs) have emerged as a potential photocatalyst owing to their remarkable optoelectronic properties. However, the poor stability and insufficient charge transportation efficiency of this type of materials have hindered their applications in the photocatalysis field. Herein, we decorated CsPbBr3 QDs on two-dimensional (2D) ultrathin g-C3N4 (UCN) nanosheets to develop a 0D/2D CsPbBr3/UCN composite photocatalyst. The introduction of UCN can not only improve the stability of CsPbBr3 QDs by passivating the surface ligands of CsPbBr3 QDs, but also facilitate the charge transfer due to the suited band gap alignment. Consequently, the obtained CsPbBr3/UCN heterostructure exhibited superior photocatalytic performance to both pristine CsPbBr3 QDs and UCN. This work has provided an efficient strategy for the design of CsPbX3-based heterostructure with high stability and photocatalytic activity.
