Summary: Efficient visible light photocatalytic elimination of pharmaceutical factory wastewater was achieved by introducing hybrid Ag/AgCl nanoparticles into Ti3+ self-doped TiO2 mesocrystals. The Ag/AgCl@Ti3+-TiO2 mesocrystals showed superior performance in degrading tetracycline under visible light, mainly attributed to the continuous attacks of photo-generated holes and radicals on tetracycline molecules.

Summary: Nanoparticulate double-heterojunction photocatalysts consisting of TiO2(Anatase)/WO3/TO2(Rutile) were synthesized via a sol-gel method, exhibiting synergistic effects in the degradation of methyl orange under both UV and visible light. The degradation rate of the best catalyst was found to depend mainly on dye concentration, as opposed to diffusion-controlled processes seen in pure oxides. The successful formation of a double heterojunction in the system led to enhanced photoactivity compared to individual oxides and commercial TiO2 P25, confirmed through various analyses.

Summary: In this study, magnetic reduced graphene oxide (rGO) encapsulated hexagonal FeTiO3 (FTO@rGO) nanosheets were synthesized for efficient degradation of venlafaxine (VLF) through photo-Fenton processes. The addition of rGO accelerated the migration of photo-generated electrons and improved the Fe2+/Fe3+ cycle, resulting in higher VLF degradation rate. The encapsulation of rGO also reduced Fe leaching and directed H2O2 activation at the FTO@rGO interface. By comprehensively analyzing intermediate products, the degradation pathway of VLF was determined.

Summary: Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have been proven to be efficient catalysts for photocatalytic hydrogen evolution due to their tunable functionalities, permanent porosity, excellent visible light response, and physicochemical stability. In this study, a series of photocatalysts (NUBC) were prepared by loading different amounts of Zr-UiO-66-NH2 onto a benzoic acid-modified covalent triazine-based framework (BC). The resulting NUBC catalysts exhibited a type-II Z-scheme heterojunction structure formed via amide covalent bonds between NU and BC. The optimal loading of NU on BC was 30 wt.% (30NUBC), which showed a significantly higher photocatalytic H-2 evolution rate compared to NU and BC alone. The synergistic effect between the type-II Z-scheme heterojunctions and amide bonds contributed to enhanced visible light harvesting and improved charge transportation and separation. Furthermore, the NUBC catalysts showed excellent reusability and stability. Overall, this work provides insights into the design of novel MOF/COF hybrid materials and offers a systematic exploration of their photocatalytic H2 evolution properties.

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.
