Summary: In this study, a three-dimensional Ag@ZnSe structure was formed by cosputtering Ag and ZnSe on a polystyrene template. The surface morphology and composition of the structure were controlled by adjusting the sputtering power of ZnSe, and the introduction of ZnSe also introduced a charge-transfer effect. The catalytic activity of the substrate was observed due to the charge-transfer effect, and the catalytic degradation of malachite green (MG) was successfully monitored using in situ surface-enhanced Raman scattering (SERS). The study provides insights into the synergistic effects of electromagnetic mechanism and charge transfer, as well as a new perspective on photocatalysis and catalytic process monitoring.

Summary: The invention of defect-engineering motivated Z-scheme photocatalytic complexes has provided a novel approach to achieve modified visible-light driven photocatalytic performance. By systematically studying the role of the Sn2+/Sn4+ redox couple in the photocatalytic process, it is demonstrated that the deficient Sn2+ reactive sites can facilitate small molecule adsorption and enhance interfacial carrier separation and transfer. This work contributes to a more in-depth exploration of Z-scheme photocatalytic-system construction and the development of defect-engineering approaches with high photocatalysis performance.

Summary: A 3D flower-like hierarchical mesoporous Bi4O5I2/MoS2 photocatalyst was fabricated, and the introduction of MoS2 extended the photoresponse to the near-infrared region and showed significant photothermal effect. The photocatalytic efficiency in the degradation of toxic dichlorophenol and the reduction of hexavalent chromium was significantly improved, and the photocatalytic hydrogen production rate was also greatly enhanced. The excellent performance can be attributed to the promoted photothermal effect and the formation of compact Z-scheme layered heterojunctions.

Summary: Combining morphology modification with heterojunction is an effective approach to enhance the photocatalytic activity of TiO2-based photocatalysts for wastewater treatment. In this study, a novel flower-like TiO2/Bi2O3 (FTB) photocatalyst was developed by depositing Bi2O3 nanoparticles on the surface of flower-like TiO2 (FT). The successful formation of p-n heterojunction between flower-like TiO2 and Bi2O3 was confirmed, which facilitates efficient charge separation. Due to the narrow bandgap of Bi2O3 and the unique flower-like microstructure, FTB exhibits a photocurrent 1.67 times higher than that of FT, resulting in a higher photo-degradation rate (92.7%) of levofloxacin compared to FT photocatalyst (approximately 80%). Moreover, FTB demonstrates excellent anti-interference capability towards environmental factors and good cyclability. This work provides new insights into the development of TiO2-based photocatalysts with advanced performance for antibiotic removal.

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.
