Summary: A simple wet chemical method was used to prepare p-n heterojunction photoelectric composites (Bi2S3@g-C3N4) in this study. The formed p-n junctions facilitated charge transfer and strongly suppressed electron-hole pair recombination, thereby enhancing the photoelectrochemical (PEC) characteristics. The prepared composites showed a 2.98 times higher photocurrent intensity compared to the pristine g-C3N4 material. The novel PEC sensor composed of Bi2S3@g-C3N4 composite material demonstrated sensitive and selective detection of chlorpyrifos.

Summary: In this study, g-C3N4@CdS composites were used as sensing elements in a photoelectrochemical platform for the rapid, selective, and sensitive detection of L-cysteine. The system exhibited a wide determination range (5-190 μM), a very low detection limit (1.56 μM), fast response time, and good long-term stability (approximately 1 month). The g-C3N4@CdS composites provided better optoelectronic function than bare CdS materials due to their high photon-to-current conversion efficiency and excellent anti-photocorrosion properties. Additionally, without any separation procedures, low concentrations of L-cysteine were successfully detected in human urine samples, consistent with the results of chemiluminescence.

Summary: Regulating flow direction of photo-excited electrons from interior to active sites in surface is critical to enhance the photocatalytic performance. In this study, CdS and NiS nanodots were sequentially deposited onto g-C3N4 nanosheets using the photoinduced chemical reduction process. The resulting NiS/CdS/g-C3N4 hybrid composite showed significantly enhanced activity under visible light, and achieved a hydrogen evolution rate 2.4 times higher than that of g-C3N4. The enhanced activity was attributed to the favorable band overlapping and promoting charge separation, rather than increasing light absorption. Femtosecond time-resolved transient absorption spectroscopy (fs-TAS) revealed that the photo-excited electrons originated from g-C3N4, migrated unidirectionally to CdS, and finally reached NiS, which was facilitated by the precise regulation of CdS and NiS positions on g-C3N4 surface. This study provides insights into the electron transfer kinetics and processes in multi-component systems and offers a new avenue for the construction of stable photocatalysts with high activity.

Summary: Piezocatalysis is a new technique that converts mechanical energy into chemical energy. In this study, an organic Fe-metal organic framework (MOFs) was used as a piezoelectric material to purify water. The results showed that MIL-100(Fe) removed 92% of CBZ in 30 minutes using ultrasonication, which was significantly higher than using either the individual MIL-100(Fe) or ultrasonication alone. This was due to the generation of an electric field and band structure modulation in MIL-100(Fe) under mechanical stress, promoting free charge migration and reactive oxygen species production.

Summary: This study developed a g-C3N4 with N2C-type defects/MoO3 Z-scheme photocatalyst (D-CN/MoO3) for the degradation of microcystin (MC-LR) in visible light. The D-CN/MoO3 could photodegrade 100% of MC-LR within 25 min, which was significantly higher than pure g-C3N4. The degradation mechanism was found to be the selective attack of 1O2 on the Adda side chain of MC-LR and subsequent decarboxylation reaction of h+, leading to effective mineralization and reduced toxicity of MC-LR. The D-CN/MoO3 also demonstrated excellent stability and adaptability, showing potential for decontamination of MC-LR in eutrophic water.

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.
