Metal‐Organic Frameworks Derived Electrocatalysts for Oxygen and Carbon Dioxide Reduction Reaction

Abstract

The increasing demands of energy and environmental concerns have motivated researchers to cultivate renewable energy resources for replacing conventional fossil fuels. The modern energy conversion and storage devices required high efficient and stable electrocatalysts to fulfil the market demands. In previous years, we are witness for considerable developments of scientific attention in Metal‐organic Frameworks (MOFs) and their derived nanomaterials in electrocatalysis. In current review article, we have discussed the progress of optimistic strategies and approaches for the manufacturing of MOF‐derived functional materials and their presentation as electrocatalysts for significant energy related reactions. MOFs functioning as a self‐sacrificing template bid different benefits for the preparation of metal nanostructures, metal oxides and carbon‐abundant materials promoting through the porous structure, organic functionalities, abundance of metal sites and large surface area. Thorough study for the recent advancement in the MOF‐derived materials, metal‐coordinated N‐doped carbons with single‐atom active sites are emerging candidates for future commercial applications. However, there are some tasks that should be addressed, to attain improved, appreciative and controlled structural parameters for catalytic and chemical behavior.

Ligand-Assisted Controllable Growth of Self-Supporting Ultrathin Two-Dimensional Metal–Organic Framework Nanosheet Electrodes for an Efficient Oxygen Evolution Reaction

“…Numerous studies have been reported to fully demonstrate that MOFs have become excellent precursors and templates for most metal/metal oxides/metal hydroxides/porous carbon nanocomposites, and as-prepared 2D MOF nanosheets can also be carbonized to their corresponding 3D mixed metal oxides@porous carbon arrays on various conductive substrates, which can directly serve as an ideal electrode to be applied to electrochemical testing. In particular, the MOF-derived porous carbon obtained after pyrolysis can not only promote the accessibility of catalytically active sites but also improve the electrical conductivity, resulting in a significant improvement in catalytic performance. − The samples were continuously annealed at 600 °C for 2 h (named UNi-MOFNs-2@NC, Ni-MOFNs-50@NC, and Ni-MOFNs-100@NC) with a kind of indexable metallic Ni phase of a strong and wide diffraction peak attributed to amorphous carbon. The overall morphologies of UNi-MOFNs-2@NC were characterized by SEM (Figures a and S7).…”

Synthesis of Electrical Conductive Metal‐Organic Frameworks for Electrochemical Applications

“…It is possible to catalyze chemical processes using this huge surface area, such as the synthesis of hydrogen fuel. [1][2][3] MOFs can be used to detect the presence of various compounds, including poisons or pollutants. The sort of metal ions and organic linkers utilized to create MOFs may be changed to alter their tunable qualities.…”

It is possible to catalyze chemical processes using this huge surface area, such as the synthesis of hydrogen fuel [1–3] . MOFs can be used to detect the presence of various compounds, including poisons or pollutants.…”

High-Performance FeCo/NC-Mo2TiC2/Carbon Nanotube Hybrid Support Catalyst toward Oxygen Reduction for Alkaline Anion Exchange Membrane Fuel Cell

“…Kim et al reported a Co 3 O 4 nanoparticle on carbon nanotubes (Co 3 O 4 /CNTs) with E 1/2 = 0.83 V in an alkaline solution. Transition metal-based nitrogen-codoped carbon materials (M-N-C, M = Fe, Co, Cu, Mn, and Ni) have high activity, low cost, and a wide availability of raw materials, making them a promising catalyst. − Wu et al reported a Fe-N-C catalyst with a carbon nanotube that has a good effect under alkaline conditions. Najam et al reported a P, N double-doped carbon skeleton-supported monatomic Zn catalyst (Zn–N 4 P/C) has better activity ( E 1/2 = 0.86 V) and stability than Pt/C.…”
