Summary: This study investigates the effect of alkali solution on the electronic structure of H2O/g-C3N4 and the dynamic process of water splitting. It is found that alkali can promote hydrogen production in g-C3N4 by accelerating the decomposition of H2O into H+. The alkali also reduces the free energy for H2O splitting and changes the position of the rate-determining step, making it easier for H to capture excited electrons and form H2.

Summary: The further development of an efficient and sustainable water treatment requires the development of a very active and controllable photocatalyst. In this study, a CNO/g-CN photocatalyst was synthesized and shown to efficiently reduce Cr(VI) and degrade organic dyes under visible light. The unique characteristic of this photocatalyst is its low recombination rate of electron-hole pairs. This study opens an alternative route for effective binary photocatalysts in environmental remediation.

Summary: In this study, oxalic acid-induced chemically functionalized graphitic carbon nitride (OCN) was prepared using a one-pot calcination method. The OCN exhibited a highly porous structure with enhanced surface area and abundant amino groups, resulting in a maximum tetracycline removal of 92% within 90 min of visible light illumination. The increased presence of amino groups and enhanced visible light absorption were attributed to the exceptional photocatalytic efficacy of the functionalized OCN.

Summary: A solvothermal self-made composite of graphitic carbon nitride (g-C3N4) and commercially available titanium dioxide (TiO2) showed excellent capabilities for removing commercial acid green-25 (AG-25) textile dye in saline water matrix through activation by ultraviolet (UV) and visible light. The composite was characterized by various analytical techniques and it exhibited significantly higher degradation efficiency of AG-25 compared to TiO2 and pure g-C3N4 under simulated solar spectrum. The research also provided insights into the contribution of different reactive oxidative species (ROS) in the degradation process.

Summary: CeO2 sheets (CeO2-S) were hydrogen treated (CeO2-S-H2) and coupled with carboxylated g-C3N4 (C-g-C3N4) to form a 2D/2D C-g-C3N4/CeO2-S-H2 heterostructure. The introduction of oxygen vacancies in CeO2-S-H2 increased the ratio of Ce3+/Ce4+. The experimental results showed that the CO yields on 60% C-g-C3N4/CeO2-S-H2 were 2.41, 6.83, and 1.72 times higher than that of pure C-g-C3N4, CeO2-S, and CeO2-S-H2, respectively. Furthermore, the highest CH4 yields of 11.997 mu mol/g were obtained on CeO2-S-H2, indicating the effective enhancement of CH4 production by introducing oxygen vacancies. The 60% C-g-C3N4/CeO2-S-H2 heterostructure also demonstrated the best performance in ciprofloxacin degradation, suggesting that the synergistic effects of oxygen vacancy introduction and heterojunction construction promoted charge transfer and separation.
