2D Conductive Metal–Organic Frameworks: An Emerging Platform for Electrochemical Energy Storage

Abstract

Two‐dimensional conductive metal–organic frameworks (2D c‐MOFs) as an emerging class of multifunctional materials have attracted extensive attention due to their predictable and diverse structures, intrinsic permanent porosity, high charge mobility, and excellent electrical conductivity. Such unique characteristics render them as a promising new platform for electrical related devices. This Minireview highlights the recent key progress of 2D c‐MOFs with emphasis on the design strategies, unique electrical properties, and potential applications in electrochemical energy storage. The thorough elucidation of structure–function correlations may offer a guidance for the development of 2D c‐MOFs based next‐generation energy storage devices.

Lattice Matching Growth of Conductive Hierarchical Porous MOF/LDH Heteronanotube Arrays for Highly Efficient Water Oxidation

“…The formed 2D cMOF shell nanolayer is composed of metal nodes and an HHTP linker and possesses two distinct layer www.advmat.de www.advancedsciencenews.com frameworks of extended and discrete honeycomb layered structures, which form 1D channels along the c-axis via π-π and metal-metal interactions when stacked together. [25] The P3c1 space group with unit cell parameters of a = 22.130 Å, b = 22.130 Å, c = 13.310 Å and α = 90.00°, β = 90.00°, and γ = 120.00° are ascribed to the crystal plane in the cMOF shell (Figure 4b). The lattice constants of the cMOF structures are twice those of CoNiFe-LDH structure along the a, b, and c directions.…”

Two-dimensional conjugated metal–organic frameworks (2D c-MOFs): chemistry and function for MOFtronics

“…195 Benefiting from the intrinsically conductive and porous properties, 2D c-MOFs have shown excellent performance in metal-ion batteries and supercapacitors, which could function as the power sources for the above mentioned MOFtronics. [197][198][199][200][201] 6.5.1 Metal-ion batteries. Benzene-based 2D c-MOFs with dense redox active sites have been widely utilized as active cathode materials for lithium/sodium-ion batteries (Fig.…”

Visible Light–Initiated Synergistic/Cascade Reactions over Metal–Organic Frameworks

“…In addition, the recently fast developed 2D ultrathin MOF nanosheets would also be ideal candidates to use for the construction of multifunctional MOFs because in these ultrathin 2D MOFs, the transportation of the photogenerated charge carriers can be shortened and they can also be more exposed active catalytic sites for the reactions. [ 148,149 ] Surely, the development of highly efficient MOF‐based catalytic systems should rely on knowledge of the electronic structure of MOFs and their excitation kinetics. Time‐resolved absorption spectroscopy can provide information on the formation, decay, recombination, and transfer processes of photogenerated charge carriers, which is important information for the understanding of the photocatalytic mechanisms and for a better design of photocatalytic systems.…”
