“…The size of the MOF particles is inversely related to their surface area/volume ratio, so this variation will have an effective role in improving the catalytic activity. 37 The images were obtained at varied magnifications between 50 and 100 nm. Numerous benefits are introduced by this diverse array of nanosphere architectures, such as a massive surface area, biological activity, and catalytic activity.…”

“…In recent years, numerous studies have proposed various modification methods to alleviate membrane fouling issues, such as modification with inorganic ion exchangers, oxidation of graphene, metal-organic frameworks (MOFs), and others [19][20][21][22][23][24]. Polyvinylidene fluoride (PVDF) is a commonly used material for ultrafiltration membranes.…”

In this study, molecules of propyl gallate (PG) and polyethylene glycol methacrylate (PEGMA) were covalently bonded via a transesterification reaction and subsequently grafted onto polyvinylidene fluoride substrates using a homogeneous radiation grafting technique. The enhancement of the membranes’ hydrophilicity with the increment of the grafting rate was corroborated by scanning electron microscopy imaging and measurements of the water contact angle. At a grafting degree of 10.1% and after a duration of 4 min, the water contact angle could decrease to as low as 40.1°. Cyclic flux testing demonstrated that the membranes modified in this manner consistently achieved a flux recovery rate exceeding 90% across varying degrees of grafting, indicating robust anti-fouling capabilities. Furthermore, these modified membranes exhibited significant antioxidant ability while maintaining antifouling performance over 30 days. The ability of the modified membranes to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS+) free radicals remained nearly unchanged after being stored in pure water for 30 days, and the flux recovery rate remained above 95% after immersion in sodium hypochlorite solution for 30 days. Among the tested membranes, the PVDF-g-PEGMAG modified membrane with a grafting degree of 7.2% showed the best antioxidant effect.

“…ZIFs are a new porous structural material that combine the advantages of MOFs with the characteristics of zeolite material [21][22][23][24][25]. ZIFs generally have higher thermal and chemical stability than other MOFs, which lays a good foundation for the application of ZIFs in catalysis, gas storage, and separation [26,27]. The synthesis of ZIF-8 is typically carried out using solvothermal or solvent evaporation methods, where metal ions and organic ligands come together to form a crystal structure under specific conditions.…”

The development of photocatalysts for organic degradation is a hot research topic. In this study, CdZnS was selected as the carrier, and ZIF-8 was combined with it to explore the photocatalytic performance of the composite. In addition, the compound material, CdZnS@ZIF-8, was used as a photocatalyst for the decomposition of methylene blue dye, and the performance of pure CdZnS and pure ZIF-8 was compared. The photocatalytic efficiency of CdZnS@ZIF-8 was significantly higher than that of the other two. In the experimental reaction, the amount of catalyst was 0.04 g, the pH value was 7, the initial concentration of methylene blue aqueous solution was 20 mg/L, and the degradation of methylene blue in 50 mL aqueous solution could reach 99.5% under visible light irradiation for 90 min, showing excellent photocatalytic efficiency in the visible light range. It demonstrated excellent photocatalytic function in the visible light region, and the electron transfer phenomenon at the interface occurred in the het-junction and the separation of the photo-generating electron–hole as an electron acceptor of ZIF-8 further promoted the photocatalytic effect.
