Summary: The presence of pre-adsorbed water in MIL-53(Cr) can significantly impact the adsorption and separation of C8 aromatics, leading to preference reversal between xylene isomers and increased selectivity towards ethylbenzene. Molecular simulation also suggests that water molecules in the pores tend to package around certain components, hindering their interaction with the framework or other adsorbates.

Summary: In this study, composite microspheres FMCS-1 were prepared by modifying MIL-125-NH2 with Fe3O4 and chitosan. The introduction of chitosan effectively prevents the stacking of MOFs, and Fe3O4 solves the problem of difficult separation. FMCS-1 exhibited a maximum adsorption capacity of 109.46 mg/g for toxic Cr(VI) at pH = 2. The adsorption of Cr(VI) by FMCS-1 was chemical adsorption and FMCS-1 showed acid resistance and recyclability. This work expands the application of MOFs in water treatment and provides an effective adsorbent for Cr(VI) removal.

Summary: This study reports the impact of adding varying loadings of NZF nanoparticles into a TiO2 photoanode on the performance of DSSCs sensitized with natural and commercial dye molecules. The findings show that NZF greatly improves the photoconversion efficiency of the DSSCs, with the greatest improvement observed at an optimum loading of 50% w/w. The improved performance can be attributed to higher dye loading, improved electron transportation, and reduced electron recombination rates.

Summary: Water pollution, caused by micropollutants such as antibiotics and organic dyes, is a serious global threat to human health and the environment. Nanostructured semiconductors, particularly bismuth-based photocatalysts, have gained significant interest for their potential in advanced oxidation processes using photocatalysis for sustainable wastewater treatment. Recent developments and improvements in photocatalytic capabilities of bismuth-based photocatalysts, including morphological modifications, doping, and the creation of Z-schemes, Schottky junctions, and heterojunctions, are thoroughly covered in this review. The review also discusses general photocatalytic mechanisms and potential degradation pathways for antibiotics and dyes in wastewater, as well as areas that require further attention and study for real-world applications.
