Summary: This study investigates the synergistic effect of g-C3N4 and CdS on photocatalytic degradation of organic dye pollutants. The results show that the g-C3N4/CdS heterojunctions have remarkable visible-light photocatalytic properties, effectively enhancing the absorption of visible light and inhibiting the recombination of photogenerated carriers. The g-C3N4/CdS heterojunctions exhibit significantly improved photodegradation activities compared to pure g-C3N4 and CdS. The different degradation behaviors of the composite photocatalysts on mixed pollutants were studied, and the possible reaction mechanism of the photocatalytic degradation was explored.

Summary: The novel polycationic Pp-x@g-C3N4 composite showed superior hydrogen evolution activity in water splitting compared to g-C3N4 and Pp-0. Despite the weakening effect of lengthened methylene chains in the polymer, the conjugated double bonds, solubilization, and dispersion of Pp-x polycationic surfactants made Pp-x@g-C3N4 outperform g-C3N4 in water splitting.

Summary: A porous material based on a beta-SiAlON ceramic matrix was synthesized by combustion of ferrosiliconaluminum in a nitrogen atmosphere. The material was used as a substrate for a graphitic carbon nitride (g-C3N4)-based photocatalyst with high stability and activity for murexide oxidation in aqueous solution under visible-light irradiation. The preparation of g-C3N4 supported on the porous ceramic composite shows potential as an advanced technology for fabricating photocatalysts to remove organic pollutants from water.

Summary: Composite materials formed by titania and graphitic C3N4, such as C3N4/TiO2 and C3N4/SrTiO3/TiO2 heterojunctions, have attracted significant interest as efficient photocatalysts. The different behavior of the two heterojunctions can be rationalized based on density functional theory calculations, showing a reversal in the interface dipole and junction nature in the ternary system.
