Description

Key Properties & Advantages
MIL-101(Fe) (KAR-F49)’s performance stems from its iron-based framework and hierarchical porous design:

Tunable Surface Chemistry: Easily modified via functional group incorporation (e.g., -NH₂, -COOH, -OH), enabling tailored adsorption affinity and selectivity for specific target molecules (e.g., pollutants, gases, organic compounds).
Hierarchical Porosity: Features a range of pore sizes (0.3–2.0 nm), facilitating efficient mass transport of both small and moderately sized molecules—critical for adsorption and catalytic reactions where diffusion limits performance.
High Surface Area (≥1000 m²/g): Provides abundant active sites for adsorption, catalytic reactions, and functionalization, enhancing efficiency in all applications.
Iron-Mediated Activity: Iron nodes contribute Lewis acidity and redox properties, supporting:
Intrinsic catalytic activity for oxidation/reduction reactions.
Photocatalytic performance (low band gap) under visible light.
Robust Stability: Maintains structural integrity in aqueous environments (pH 3–9) and moderate temperatures (up to 300°C under inert conditions), ensuring durability in industrial workflows.
Uniform Particle Size (1–3 μm): Ensures consistent packing in columns, uniform dispersion in composites (e.g., membranes), and reliable performance in scalable processes.
Core Applications
Customizable Adsorption & Separation
MIL-101(Fe) (KAR-F49)’s modifiable surface makes it ideal for targeted adsorption:

Functional Group Tuning: By adjusting surface 官能团 (e.g., adding amine or carboxyl groups), adsorption capacity and selectivity for specific adsorbates (e.g., heavy metals, dyes, pharmaceuticals, CO₂) can be significantly enhanced.
Pollutant Removal: Efficiently captures organic and inorganic contaminants from water and air, with modified variants achieving high selectivity for priority pollutants (e.g., Cr(VI), bisphenol A).
Catalyst & Carbon-Based Electrocatalyst Production
Catalytic Reactions: Serves as a catalyst or catalyst support for organic transformations (e.g., oxidation of alcohols, coupling reactions) and environmental remediation (e.g., degradation of persistent organic pollutants).
Carbon-Based Electrocatalysts: Thermally decomposed to produce iron-doped porous carbon materials, which exhibit excellent performance in electrocatalytic reactions (e.g., oxygen reduction reaction, hydrogen evolution reaction) for energy storage and conversion devices (e.g., fuel cells, batteries).
Photocatalysis
Visible-Light Activity: Its low band gap enables efficient light absorption, driving photocatalytic reactions such as:
Water splitting for hydrogen production.
Degradation of organic pollutants under solar light.
CO₂ reduction to value-added chemicals, supporting sustainable energy research.
High-Selectivity Membranes
Functionalized Membrane Design: When integrated into polymer or ceramic membranes, modified MIL-101(Fe) enhances selectivity for target molecules (e.g., water/ethanol separation, gas mixtures like CO₂/CH₄), improving efficiency in industrial separation processes.
