Summary: The development of high-efficient photocatalysts for CO2 reduction is crucial for addressing global energy and environmental challenges. This study presents a 2D/2D hierarchical heterostructure of NiFeV layered double hydroxide (LDH) nanosheets and g-C3N4, which significantly enhanced the photocatalytic performance. The weight ratio of g-C3N4 to NiFeV-LDH had a significant impact on the catalytic activity, with the highest yields of CH4 and CO generated when the ratio was 15%.

Summary: This study revealed that g-C3N4 nanosheets doped with 2.16% oxygen content in the O-N1 position showed the highest photocatalytic activity in degrading Rhodamine B under visible light irradiation, with a degradation rate of 99%. This improvement in degradation was attributed to the reduced oxygen content of O-N1-doped g-C3N4 nanosheets, as opposed to normal O-N2-doping.

Summary: A highly active Pt/g-C3N4 photocatalyst was successfully prepared by successive combination of thermolysis, chemisorption, and reductive treatment. The prepared material showed remarkable photocatalytic activity in hydrogen evolution reaction, with a high rate of H-2 evolution per platinum atom loaded and among the highest reported net rates to date. The unique structure of the material, with a branchy net of pores, facilitated efficient access of reagents and expulsion of products, leading to the excellent performance. The self-catalyzed hydrogenation of the Pt/g-C3N4 composites played a crucial role in the formation of the noted morphology. The study demonstrated the potential of this approach for large-scale applications in hydrogen production.

Summary: Nickel-decorated manganese oxynitride/graphene nanosheet nanocomposites were prepared and demonstrated as efficient photocatalysts for the degradation of acetylsalicylic acid (ASA) under visible light. The nanocomposites showed higher efficiency and structural stability compared to manganese oxide (MnO) and manganese oxynitride (MnON) nanoparticles, attributed to their larger specific surface area and smaller band gap. Additionally, the nanocomposite exhibited insignificant cytotoxicity, making it a promising candidate for remediation of ASA-contaminated water.

Summary: In this study, a novel graphitic carbon nitride/carbon (g-C3N4/C) composite was prepared by one-step calcination of a mixture made of potassium hydroxide (KOH), melamine, and microplastics. The obtained composite can effectively produce hydrogen peroxide (H2O2) at a high rate under visible light irradiation. The modification of KOH and the introduction of graphitic carbon contribute to the enhanced electron absorption ability, adsorption ability of O-2, and reduction ability, resulting in improved photogeneration performance of H2O2.

Summary: Photocatalytic radical fluoroalkylation is an important method to prepare organofluorine compounds. This study introduces a cost-effective and recyclable heterogeneous photocatalysis using cyano-modified graphitic carbon nitride as the photocatalyst. The photocatalytic process is attributed to the long-lived triplet excited states and the strong interaction between the catalyst and substrate. Moreover, the catalyst shows high performance, wide reaction scope, and can be easily recovered and reused for multiple catalytic cycles.

Summary: In this study, a dysprosium-containing mono-EMF with a C-84 cage, possessing rare D-2(21) symmetry, was successfully synthesized. Theoretical calculations revealed that the encapsulation of a trivalent Dy ion in the carbon cage is energetically more favorable than other C-84-based mono-EMFs. This work not only expands the trivalent mono-EMF family but also provides insights into the unique structures and stabilities of such novel EMFs.
