Summary: This study reports the development of a recyclable dual Z-scheme g-C3N4/BiVO4/CuFe2O4 heterojunction as an efficient photocatalyst for the activation of peroxymonosulfate (PMS) under visible light illumination. The novel photocatalyst exhibited enhanced photocatalytic degradation behavior for levofloxacin (LEV) compared to single-component counterparts. The addition of PMS further improved the removal efficiency, which was attributed to the synergistic effect between photocatalysis and PMS activation. The system also demonstrated excellent mineralization ability, low degradation product toxicity, and adaptability to various solution conditions.

Summary: The stoichiometric water splitting using a solar-driven Z-scheme approach is a promising solution to the growing demand for renewable energy and environmental concerns. In this study, a robust Z-scheme system was constructed using only tungsten oxides, enabling efficient visible-driven water splitting. The system achieved high H2 and O2 production rates in a neutral solution, with an apparent quantum yield of 6.06% at 420 nm. The selective production of H2 and O2 was attributed to the preferential adsorption of iodide and iodate on the respective photocatalysts. This liquid Z-scheme system, combined with efficient shuttle molecules, offers a safe and separated H2 and O2 evolution process.

Summary: A cost-effective photocatalyst, Bi/BiVO4-CdS, with efficient electron-hole separation efficiency and excellent light absorption capacity, has been successfully developed for the degradation of tetracycline hydrochloride (TCH) from wastewater. This photocatalyst exhibits superior performance in TCH degradation, with a degradation ratio of 85.5% within 30 minutes and enhanced stability over multiple cycles, attributed to the generation of h(+), center dot O-2(-), and center dot OH reactive species. Intermediates identified by HPLC-MS suggest proposed pathways for the photocatalytic degradation of TCH using Bi/BiVO4-CdS.

Summary: The study presents the construction of a novel heterojunction structure by in-situ growth of ultrathin PCN on electrospun Bi2WO6 nanofibers for enhanced photocatalytic degradation of tetracycline. The gas-solid reaction enables the formation of well-contacted interfaces between PCN nanosheets and Bi2WO6 nanofibers, resulting in accelerated charge carriers separation and transfer. The optimized PCN/Bi2WO6 photocatalyst exhibits a significant tetracycline degradation rate of 89.5% under visible light, which is 1.4-fold and 2.0-fold higher compared to pure PCN and Bi2WO6 photocatalysts, respectively. The innovative design philosophy opens up new possibilities for the development of efficient Z-scheme heterostructured photocatalysts for antibiotic degradation.

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.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
