Effect and mechanism of inorganic anions on the adsorption of Cd2+ on two-dimensional copper-based metal–organic framework

A Bifunctional Three-Dimensional Zn(II) Metal–Organic Framework with Strong Luminescence and Adsorption Cr(VI) Properties

“…The XPS also proved that the zinc ions in 3D-Zn-MOF were all Zn(II). The arrangement of extranuclear electrons in Zn(II) was 3d 10 . And literature 29 had also proven that Zn(II) complexes with a 3d 10 arrangement typically exhibited good fluorescence performance.…”

“…The basic structure of MOFs consists of metal ions (usually transition metals such as copper, zinc, and nickel) as centers, connecting multiple organic ligands (usually electron-rich organic acid molecules) to form a three-dimensional network. − The organic ligands of MOFs can form spatial configurations of different shapes and sizes through coordination with metal ions, which are called pores . The pore structure of MOFs can be designed and regulated according to specific requirements, enabling MOFs to have highly adjustable functions such as adsorption, , separation, , photocatalysis, − and energy storage. − In addition, MOFs have many characteristics and advantages, − including high adjustability, large pore volume and surface area, porous structure, low density, and high chemical stability. These characteristics make MOFs have broad application potential in fields such as fluorescence, adsorption, gas separation, catalytic reactions, − energy storage, − and sensing. − For example, fluorescent MOFs can achieve different fluorescence characteristics (optoelectronic devices, biological imaging, sensors) by selecting appropriate metal ions (Zn 2+ , Cd 2+ , Ag + , and rare earth metal ions) and designing organic ligands.…”

Effects of exogenous chloride ions on the migration and transformation of Cd in a soil-rice system

“…During the heading and filling stages, the Cd concentrations in rice treated with T1-T4 were notably lower than those in the Ca(NO 3 ) 2 treatment group (CK1-CK4). This difference is attributed to the stronger coordination ability of Cl − compared to NO 3 − , which enables Cl − to form more stable complexes with Cd 2+ (general formula CdCl n 2−n ) (Li et al, 2024). The specific composition of these complexes varies depending on the relative concentrations of Cd and Cl − .…”

Performance and Mechanism of the Modified Group Regulated the MIL-101(Fe) Type Fenton-like Catalysts

“…Compared with traditional porous materials, MOFs have a higher specific surface area, larger porosity, and diverse and adjustable structures . They are widely used in catalysis, − sensing, adsorption, − and other fields. − MIL-101(Fe) and its derivatives are novel porous materials in MOFs. ,− They are constructed through organic ligands such as Fe(III) and terephthalic acid and have advantages such as large specific surface area, high porosity, and good thermal and chemical stability. They have been studied in the removal of organic pollutants through adsorption, photocatalytic degradation, and Fenton-like catalysis .…”
