Summary: In this study, ultrathin wavy-structured GCN nanosheets were synthesized using a chlorine-mediated strategy to enhance photocatalytic activity. The enhanced activity was attributed to the in-situ self-exfoliation of GCN and the introduction of nitrogen-defects, which increased active sites and improved light absorption capacity. This work provides a new bottom-up two-step strategy for structural regulation of GCN towards enhanced photocatalytic performance.

Summary: The study investigated the dynamics of hole transfer from Pt-loaded sol-gel-prepared graphitic carbon nitride photocatalyst, using different adsorbed hole acceptors and a sacrificial agent. A significant increase in H-2 production was achieved by employing phenothiazine as the hole acceptor, with continuous H-2 production for 3 days. The charge-transfer dynamics of the photocatalytic process in the presence of hole acceptors were examined through time-resolved photoluminescence and in situ electron paramagnetic resonance studies.

Summary: A heterostructure based on exfoliated graphitic carbon nitride coated by a porous carbon layer was fabricated and tested as a photocatalyst for hydrogen evolution. The catalyst exhibited significantly higher photoactivity compared to the reference material, which could be attributed to the highly developed specific surface area, improved carrier transfer and separation, and effective suppression of recombination.

Summary: Heterogeneous photocatalysis is an ideal method for eco-friendly synthesis of value-added chemicals, but its scalability is hindered by limited photon penetration and inefficient utilization of catalytic active sites. Combining heterogeneous photocatalysis with flow systems can optimize light absorption and mass transfer, but an affordable and practical design of the flow system and immobilization method of the photocatalyst are still lacking. In this study, a flow system using anchored graphitic carbon nitride on porous silica was developed for gram-scale heterogeneous photocatalytic synthesis of azoxybenzene and its derivatives. The hydrogen bonds formed between the graphitic carbon nitride and tetramethoxysilane precursor prevent catalyst leaching and enable high selectivity, efficiency, and durability in photocatalytic flow synthesis.

Summary: Graphitic carbon nitride (g-C3N4) and CuO nanoparticles doped g-C3N4 (Cu-g-C3N4) exhibit high photocatalytic antialgal activities against harmful algae, with Cu-g-C3N4 showing stronger activity due to better aggregation and higher light utilization efficiency. The presence of humic acid (HA) inhibits the antialgal activity of g-C3N4 but has no effect on Cu-g-C3N4, suggesting that CuO nanoparticles in Cu-g-C3N4 play a role in mitigating the inhibition effects of HA. This study provides insights into the inhibition mechanisms of natural organic matter on g-C3N4 photocatalytic antialgal activity and optimization strategies for environmental applications.

Summary: We investigated the pyrolysis process of copper-containing metal-organic frameworks under high pressure and demonstrated the influence of applied pressure on the morphology and electrocatalytic performance of the resulting products in oxygen-related reactions. High-pressure and high-temperature syntheses were conducted at different pressures, and Cu@C products were obtained except for the experiment at 2.5 GPa. The morphology of the copper incorporated into the carbon matrices varied with increasing pressure, suggesting the influence of copper transportation during pyrolysis. Electrochemical measurements revealed that all samples showed activity in the oxygen reduction reaction, with the product obtained at 0.5 GPa also exhibiting oxygen evolution reaction. Despite the absence of co-catalysts, the overall performance of the 0.5 GPa-treated product in ORR/OER was excellent among Cu-based bifunctional materials, attributed to the presence of Cu(iii) species in the nano-thick copper shell structure.

Summary: We investigated the possibility of detecting water vapor through chemiluminescence using a popular chemical light reaction. The release of H2O2 from sodium percarbonate upon exposure to water vapor was confirmed by mass spectrometry in a vacuum. Chemiluminescence was observed when the mixed reagents were exposed to water vapor, allowing for the detection of faulty points in water barrier films and real-time observation of their failure during bending tests of flexible packing materials. Molecular dynamics simulation was used to study the diffusion of H2O2 molecules in polymers.

Summary: Co (x) Fe3-x O4(CFO)/Pt bilayers prepared by molecular beam epitaxy were studied for the anomalous Hall effect and X-ray magnetic circular dichroism (XMCD). It was found that the anomalous Hall effect is due to a magnetic proximity effect at the CFO/Pt interface. The XMCD signal in the Pt L-edge was only observed in the sample deposited at 600°C, indicating that the magnetic proximity effect is sensitive to the interface structure. Transmission electron microscopy images of the CFO/Pt interface and XMCD measurements of Co and Fe L-edges did not show direct evidence of interfacial atomic diffusion or alloying.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
