Summary: The construction of a sulfur doped g-C3N4/MIL-101(Fe) Z-scheme heterostructure improved the separation and migration rate of photo-induced carriers, resulting in enhanced photocatalytic activity for the degradation of methylene blue under visible light. The superior performance is attributed to the favorable band energy levels of the Z-scheme heterojunction formed between MIL-101(Fe) and g-C3N4.

Summary: Photocatalytic degradation is an environmentally friendly method for reducing organic contaminants in wastewater. Highly efficient 0D/2D Bi2MoO6/g-C3N4 heterojunctions were successfully assembled by a one-step hydrothermal method to remove the pollutant 1-naphthol. The photocatalyst exhibited exceptional degradation efficiency due to matched band structures and tightly connected heterojunctions, preventing the recombination of photogenerated carriers. This work introduces a novel method for one-step preparation of 0D/2D photocatalysts and advances the utilization of photodegradation for organic pollutants.

Summary: Bi2MoO6/g-C3N4 photocatalysts with different mass ratios were prepared and characterized. Tetracycline was used as the target contaminant for evaluation. The composite with g-C3N4 mass ratio of 8% showed the highest photocatalytic activity, degrading 97.5% of tetracycline under visible light in 120 minutes, which was 6.5 and 3.3 times higher than pure Bi2MoO6 and g-C3N4, respectively. The enhanced photocatalytic ability was attributed to the matched band structure and tightly connected heterojunction.

Summary: This study presents the assembly of a new ternary heterojunction (g-C3N4/MnWO4/NiS). The g-C3N4/MnWO4/NiS exhibited outstanding visible light absorption and high carrier separation, leading to enhanced photodegradation performance (96.7% of methylene blue, MB) compared to g-C3N4 and MnWO4. The contact region between g-C3N4 and MnWO4 efficiently facilitated rapid separation of charge carriers through NiS cocatalyst, creating binding sites between g-C3N4 and MnWO4 semiconductors. The mechanisms for photocatalytic degradation over the g-C3N4/MnWO4/NiS heterostructure were proposed and verified.

Summary: In this study, a 2D/2D binary junction GCM, formed by combining graphitic-carbon nitride (g-C3N4) and molybdenum disulphide (MoS2), was synthesized and tested for the degradation of sulfasalazine (SUL) under visible-light irradiation. The results showed that GCM-30% exhibited high efficiency in degrading the antibiotic, surpassing the pristine g-C3N4 and MoS2, due to enhanced visible-light absorption, high charge carrier separation, and high redox ability.

Summary: S doping in a highly reactive hollow tubular g-C3N4 isotype heterojunction (SCN-CN) enhances visible light absorption and directs the transfer of electrons and holes. The tubular structure of SCN-CN facilitates electron transfer in the longitudinal direction, reducing charge carrier recombination. Experimental and theoretical studies were conducted to analyze the optical properties, electronic structure, and electron transfer of SCN-CN.
