Summary: Textile industries have a significant impact on wastewater contamination. Conventional wastewater treatment methods are expensive and produce toxic by-products, while advanced oxidation processes, particularly heterogeneous photocatalysis, have shown promising results in degrading toxic chemicals. This study prepared a metal-free graphitic carbon nitride (g-C3N4) using a simple thermal method and depositing it on the surface of alumina ceramic rings. The immobilized graphitic carbon nitride demonstrated excellent photocatalytic properties for degrading methylene blue under simulated solar light irradiation.

Summary: This study focused on the interaction of different proteins with 2D graphitic carbon nitride nanosheets decorated with gold nanoparticles and their influence on visible-light-induced photocatalytic activity. The presence of proteins was found to control the kinetics of the photocatalytic activity of the nanocomposites, with different proteins either enhancing or inhibiting the photocatalytic activity. The mechanistic understanding developed in this study can be useful in controlling the photocatalytic activity kinetics of semiconductor-based photo-catalysts using proteins as activators or inhibitors.

Summary: This study proposes the use of boron to modify the structure of graphitic carbon nitride, enhancing its photocatalytic activity. The choice of boron precursor affects the positions at which boron atoms replace carbon and nitrogen in the structure, leading to significant effects on photocatalytic activity. Specifically, the sample modified with NaBH4 shows the highest oxidation rate and selectivity.

Summary: The study investigated the activation of persulfate in the presence of blue LED light using acetic acid modified graphitic carbon nitride and its application in metronidazole removal. The results showed an improvement in specific surface area and reduced charge transfer resistance in ACN. The main reactive species identified was sulfate radicals, while holes in the valence band of ACN played a minor role in metronidazole removal.

Summary: This study reports the simultaneous enhancement of surface and bulk carrier separation of g-C3N4 for the selective reduction of CO2 to CH4 by coupling with dual functional ZnS. The introduction of ZnS acts as a cocatalyst to capture photogenerated electrons and forms a polarization electric field to drive charge separation. Under concurrent vibration and visible-light irradiation, ZnS/g-C3N4 demonstrates significantly enhanced piezo-photocatalytic activity for CO2 reduction.

Summary: Among different types of semiconductor photocatalysts, MoS2 hybridized with graphitic carbon heterojunction has shown great potential due to its static chemical properties, suitable band structure, and easy synthesis. The study revealed the physiochemical and surface characterizations of the hybridized heterojunction nanocomposite, with diffused reflectance spectroscopy showing the tailored energy band gap. The efficient electron/hole pair separation, increase in redox species, and utilization of solar range led to greater degradation efficacy of g-C3N4/MoS2 heterojunction.

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: Graphitic carbon nitride (g-CN) is a transition metal free semiconductor that mediates photocatalytic reactions through proton-coupled electron transfer (PCET) mechanism. The active sites for PCET are identified as the 'triangular pockets' on the edge facets of g-CN. Using excited state PCET, g-CN can selectively cleave X-H bonds with approximately 100 kcal mol(-1) bond dissociation free energy (BDFE), leading to the formation of 1,3-oxazolidine-2,4-diones.

Summary: Polymer-derived porous carbon was utilized as a support for iron and nickel species to create an efficient oxygen reduction reaction (OER) catalyst. By modifying the carbon with FeNi, a low overpotential for OER was achieved, comparable to that of the noble metal catalyst IrO2. This work represents a significant advancement in the development of low-cost, environmentally-friendly, and highly-efficient OER catalysts.
