Summary: This work explores the use of porous silicon as a SERS-active substrate for near-infrared 1064 nm excitation. Two methods, including the production of porous silicon photonic crystals and the deposition of gold nanoparticles, were discussed for quenching the crystal silicon band-gap photoluminescence. The capability of these substrates for SERS enhancement was evaluated and the advantages and drawbacks of both methods were addressed.

Summary: This study focuses on the synthesis of wool roll-like silver nanoflowers (AgNFs) using a mixed ethanol/water solution, which reduces the size of AgNFs and enhances the SERS substrate. The smaller size of AgNFs leads to higher intensity of characteristic bands in SERS spectrum of carbendazim (CBZ), allowing for detection at lower concentrations.

Summary: Taking advantage of metal-semiconductor junctions, functional nanocomposites have been designed and developed as active substrates for surface-enhanced Raman scattering (SERS) sensing systems. In this work, three types of nanocomposites based on manganese oxide (MnO2) nanostructures and electrochemically synthesized silver nanoparticles (e-AgNPs) were prepared, which differed according to the morphologies of MnO2. The SERS performance of these nanocomposites was evaluated using the pesticide tricyclazole (TCZ) as an analyte. The MnO2 nanosheet/e-Ag (MnO2-s/e-Ag) composite exhibited the most remarkable SERS enhancement due to its large surface area and ability to improve charge transfer efficiency.

Summary: By adding different reducing agents during the growth process of AuAg nanostars, the morphology of branches was accurately controlled, and three kinds of hyperbranched star-shaped nanostructures were synthesized. The SERS performance of the hyperbranched nanostars were all stronger than that of common AuAg nanostars. Among them, Lamellar nanostars gained the best SERS enhanced factor about 1 x 107 due to the built-in nanogaps and sharp edges. The SERS detection probes prepared with purified Lamellar nanostars had high uniformity and stability, and showed excellent sensitivity in detecting crystal violet in fish, with detection range of 0.01-10 nM and detection limit of 0.015 nM.

Summary: Mesoporous Bi2S3/ZrO2 nanocomposites were synthesized using Pluronic (F-68) as a surfactant by sol-gel process and applied for thiophene oxidation under visible illumination. Bi2S3 NPs were distributed on mesoporous ZrO2 and exhibited a greater separation rate of charge carriers and extended light response compared to pure ZrO2. The optimized 15% Bi2S3/ZrO2 showed the highest photocatalytic efficiency (100%) within 105 min of visible light illumination. The photocatalytic efficiency of Bi2S3/ZrO2 nanocomposites was significantly higher than that of pure ZrO2 NPs, and the rate constant of the 15% Bi2S3/ZrO2 photocatalyst was improved 5.25 times larger than that of pure ZrO2 NPs. The improved photocatalytic ability of Bi2S3/ZrO2 nanocomposites was attributed to the formation of heterojunction Bi2S3/ZrO2, incorporation of Bi2S3 into ZrO2 and utilization of visible light in wide wavelengths.

Summary: A novel mesoporous Ag3VO4/TiO2 nanocomposites were constructed using a low-cost sol-gel approach, showing superior visible light-induced photocatalytic abilities in tetracycline degradation compared to pure TiO2 and P-25 photocatalysts. The 3% Ag3VO4/TiO2 nanocomposite exhibited the highest photocatalytic ability among all synthesized nanocomposites, completely degrading tetracycline under visible illumination within 90 min. The increased photocatalytic ability was attributed to the efficient separation of interface charge and the synergistic effects between Ag3VO4 and TiO2. This study provides valuable insights for the development of highly effective visible light photocatalysts in practical applications.

Summary: In this study, PdO/ZrO2 nanocomposites incorporating mesoporous ZrO2 were successfully synthesized through a sol-gel process. The obtained mesoporous ZrO2 exhibited a large surface area and the desulfurization efficiency of 1.5% PdO/ZrO2 photocatalyst was significantly higher than that of bare ZrO2 NPs. The enhanced photocatalytic activity of PdO/ZrO2 can be attributed to the mesostructured ZrO2 providing active sites and improving light absorption, as well as the accelerated mobility and separation of photoinduced carriers in the S-scheme heterojunction.

Summary: In this study, WO3 nanoparticles were synthesized for the first time using a simple hydrothermal method with the assistance of polyvinylpyrrolidone (PVP). AgVO3/WO3 nanocomposites with different weight percentages of AgVO3 were successfully fabricated by impregnation-calcination processes. The 9%AgVO3/WO3 nanocomposite exhibited the best photocatalytic performance, achieving 100% degradation of Ciprofloxacin (CIP) after 120 minutes of illumination. The enhanced photocatalytic activity was attributed to the close contact between AgVO3 and WO3, which improved visible light absorption and efficient separation of charge carriers. The AgVO3/WO3 nanocomposite followed an S-scheme mechanism for charge transfer and showed high reusability and photostability. This study provides new insights into the development of highly efficient nanocomposites for environmental remediation of antibiotics.

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.
