Iron Containing Metal–Organic Frameworks: Structure, Synthesis, and Applications in Environmental Remediation

Abstract

Metal-organic frameworks (MOFs) with Fe content are gradually developing into an independent branch in environmental remediation, requiring economical, effective, low-toxicity strategies to the complete procedure. In this review, recent advancements in the structure, synthesis, and environmental application focusing on the mechanism are presented. The unique structure of novel design proposed specific characteristics of different iron-containing MOFs with potential innovation. Synthesis of typical MILs, NH-MILs and MILs based materials reveal the basis and defect of the current method, indicating the optimal means for the actual requirements. The adsorption of various contamination with multiple interaction as well as the catalytic degradation over radicals or electron-hole pairs are reviewed. This review implied considerable prospects of iron-containing MOFs in the field of environment and a more comprehensive cognition into the challenges and potential improvement.

Interfacial Engineering of MoO2‐FeP Heterojunction for Highly Efficient Hydrogen Evolution Coupled with Biomass Electrooxidation

“…[ 24,25 ] Metal–organic frameworks (MOFs) have been widely studied as a new type of porous material. [ 26,27 ] In particular, polyoxometalate (POM)‐based MOFs (POMOFs) formed by the combination of Mo or W‐based POMs and post‐transition metal (PTM) ions (Fe, Co, etc.) using a ligand, inheriting the merits of both POMs and MOFs, have attracted intensive interest.…”

State‐of‐the‐Art Advances and Challenges of Iron‐Based Metal Organic Frameworks from Attractive Features, Synthesis to Multifunctional Applications

“…With reference to other MOFs, further development of functionalized Fe‐MOFs could be expanded toward the ligand postsynthetic metalation and designing bimetallic MOFs. Our previous research can provide a guidance for the design of the Fe‐MOFs with coordinated 1D, ultrathin 2D, and interleaved 3D structure …”

“…However, the relatively poor water stability of Fe‐MOFs is commonly considered as a limiting factor for practical applications . For instance, the spillage of metal and inorganic components will cause a significant adverse effect on the reactive process and the reaction medium.…”

Magnetic iron(III)‐based framework composites for the magnetic solid‐phase extraction of fungicides from environmental water samples

“…Magnetic iron(III)-based framework composites are of great interest for biomedicine, catalysis, and separation owing to iron's low toxicity, natural abundance, redox properties, and magnetic recovery capability of magnetic iron(III)based framework composites [28][29][30]. We found MIL-101-NH 2 @Fe 3 O 4 -COOH with MIL-53-NH 2 @Fe 3 O 4 -COOH and MIL-101@Fe 3 O 4 -COOH with MIL-53@Fe 3 O 4 -COOH can be produced from the same starting materials.…”
