Two‐dimensional MOFs: Design & Synthesis and Applications

Abstract

For the past few years, two‐dimensional materials have attracted widespread attention owing to their special properties and potential applications. It is well‐known that graphene, transition metal disulfide compounds (TMDC), carbon nitride, transition metal carbonitrides (Mxenes), silene and hexagonal boron nitride are typical two‐dimensional materials. Compared with these traditional two‐dimensional materials, two‐dimensional MOF is favored by numerous researchers because of its unique structure. Based on the unique metal ion and organic ligand coordination of MOF and two‐dimensional layered structure, the applications of two‐dimensional MOF were getting serious, including catalysis, supercapacitor, gas adsorption/separation, sensors and so on. This review presents a relatively comprehensive summary of the design & synthesis and applications of two‐dimensional MOF over the past few years. Furthermore, the opportunities and challenges have been discussed to supply a promising prospect to this field.

Two‐Dimensional Metal–Organic Framework Nanosheets: Synthesis and Applications in Electrocatalysis and Photocatalysis

“…This approach not only offers a good adhesion but also improves electric conductivity. Up to date, numerous 2D MONs have been grown on nickel foam (NF), graphitic carbon, graphene, and MXenes [106] . Since all these supported 2D MOFs nanosheets aimed to improve their electrochemical performances, many examples will be discussed in the section of applications of 2D MOFs in electrocatalysis.…”

Flexible MXene‐Based Composite Films: Synthesis, Modification, and Applications as Electrodes of Supercapacitors

“…[114] As an important branch of MOF materials, 2D MOFs have aroused great interest in different fields, such as chemical sensors, catalysis, separation, biomedicine, and energy storage. [115,116] The advantages of 2D MOFs for applications in the energy storage include large specific surface areas, high intrinsic porosity, abundant accessible active sites, atomic thicknesses with short pathways and large lateral sizes to allow [87] Copyright 2020, Springer. b) CNFs.…”

Recent progress in strategies for preparation of metal-organic frameworks and their hybrids with different dimensions

“…hybrid films (~100 nm) that can be used for CO 2 separation. Zhang et al synthesized the conductive MOF film [Co 3 (HOB) 2 ] n (HOB = 1,2,3,4,5,6-benzenehexaol) using (Langmuir-Blodgett) LB technology [194] . Interestingly, this 2D film has good electrical conductivity and detects hydrogen peroxide well with an ultralow detection rate of 1.05 × 10 -8 wt%.…”
