Metal-organic framework-derived materials for electrochemical energy applications

Highly Efficient Porous Carbon Electrocatalyst with Controllable N‐Species Content for Selective CO2 Reduction

“…The large pores not only provide good pathways for fast mass transport, but also more importantly, expose a large amount of active N sites to the electrolyte for efficient CO 2 RR . Metal–organic frameworks (MOFs) have been widely used as hard templates for casting of porous carbons owing to their highly porous nature, the ability to immobilize active functional materials, and highly controllable nanostructures . However, most of this work focused on the use of oxygen‐scarce zeolitic imidazolate frameworks (ZIFs) as precursors and the derived carbon usually show limited size of pore structures .…”

Single‐Atom Iron Catalysts on Overhang‐Eave Carbon Cages for High‐Performance Oxygen Reduction Reaction

“…[8] Metal-organic frameworks (MOFs), a newly emerging class of porous crystalline materials, [9] have flourished as the promising templates/precursors for the construction of numerous porous functional materials, including carbondecorated single-atom catalysts. [10] Generally, pyrolysis of MOFs will create shrunk aggregated solids or collapsed structures. [11] To date only a few MOF-derived single-atom metal catalysts have been reported for highly active catalysis, which is mainly restricted to bulk particles with rare stretched edges as three-phase exchange spaces to boost the mass transport properties.…”

Conjugated Copper–Catecholate Framework Electrodes for Efficient Energy Storage

“…[4] Theh igh electrical conductivity and large porosity endows c-MOFs with large capacity for ions,which is advantageous for improving EDL capacitance.F urthermore, both the redox-active organic linkers and variable valence of metal centers are beneficial to pseudo-capacitance.T herefore, c-MOFs are an emerging candidate for energy storage and usually exhibit high performance and good electrochemical stability. [5] Fore xample,arecently reported 2D c-MOF (that is,N i 3 (HITP) 2 ) [6] exhibited av ery high electrical conductivity (50 Scm À1 ). However,N i 3 (HITP) 2 based supercapacitor showed moderate gravimetric (ca.…”
