Summary: Equisetnm arvense plant extract was used to prepare amorphous SiO2, which was then added to the synthesis mixture of ZIF-8 to prepare SiO2/ZIF-8 nanocomposite. The photocatalytic activity of SiO2/ZIF-8 was investigated, and it exhibited the highest activity and improved stability compared to pure SiO2 and ZIF-8. SEM and TEM images confirmed that ZIF-8 particles were distributed without aggregation on SiO2. The introduction of insulator SiO2 modified the surface state of the composite and accelerated the separation and transfer of electron-hole pairs of ZIF-8.

Summary: A novel visible-light responsive composite, aluminophosphate-5/graphene oxide (AlPO-5/GO), has been easily synthesized by hydrothermal method using GO, tri-ethylamine, pseudo-boehmite, and phosphoric acid as reactants. Copperous oxide (Cu2O) was added to modify the structure of the composite for photocatalytic applications in the visible light range. Characterization techniques confirmed the successful synthesis of the composite and revealed its suitable morphology for degradation of cationic dyes. The optimized AlPO-5/Cu2O/GO nanocomposite showed a degradation efficiency of 80.2% at 90 min, indicating its improved photocatalytic activity compared to GO/Cu2O and AlPO-5/GO.

Summary: Phthalocyanine derivatives can act as photosensitizers for the treatment of microbial infections. By modifying the structure and substituents of phthalocyanines, the interaction with microorganisms and photodynamic inactivation can be enhanced. Phthalocyanines have strong absorption and emit red fluorescence in the phototherapeutic window, and they efficiently generate reactive oxygen species to eliminate microbes.

Summary: The selective oxidation of styrene requires highly efficient, environmentally friendly, and cost-effective catalysts. In this study, Cu2O@Cu-BDC-NH2 catalysts were developed through an in situ self-assembly strategy. The optimized sample achieved high conversion and selectivity under mild conditions, thanks to the well-designed interface and porous MOF shells. Furthermore, Cu2O cuboctahedrons were also synthesized and showed good catalytic performance. This work provides a useful strategy for developing efficient and environmentally friendly heterogeneous catalysts for the selective oxidation of styrene.
