Supercritical CO2 assisted synthesis of highly accessible iron single atoms and clusters on nitrogen-doped carbon as efficient oxygen reduction electrocatalysts

Recent advances and future perspectives in MOF-derived single-atom catalysts and their application: a review

“…5D). Gao and Yang et al 89 added ZIF-8 and iron solution together into the supercritical reaction reactor, injected CO 2 until the pressure and temperature reached a certain condition and continued to react for a period of time. Then, they released the gas to obtain scCO 2 -Fe@ZIF-8, and the precipitate was pyrolyzed and treated with acid to produce the required catalyst.…”

Progress and Perspectives of Single‐Atom Catalysts for Gas Sensing

“…Most porous materials can effectively separate and package mononuclear metal precursors as their uniformly dispersed active centers and ordered pore sizes. [50][51][52][53] The metal-organic frameworks (MOFs) are assembled through the coordination between metal ions or clusters and organic ligands, which have the characteristics of clear structure, strong designability, and developed channels. SACs with specific metals can be synthesized using MOFs as supports.…”

Surface, Interface and Structure Optimization of Metal‐Organic Frameworks: Towards Efficient Resourceful Conversion of Industrial Waste Gases

“…[136][137] Researchers have attempted to expose or construct missing cluster structures to study the effect of photoactivity to verify the contribution of rational regulation of the local coordination environment near metal clusters to electron transfer kinetics and reaction kinetics. [138] zhang et al skillfully immobilized the dinuclear cluster {Fe 2 (H 2 O) 6 (Triazo) 3 } in the backbone by ligand substitution of the precursor Fe 3 -MOF and NH 2 À Fe 3 -MOF, respectively. [139] The paddle-wheel-shaped Fe 2 À Tri cluster replaces the ligand water molecules in the Fe 3 (μ 3 -O) cluster and is precisely implanted between the Fe 3 (μ 3 -O)Cl(H 2 O) 2 nodes in the metal-organic framework(Figure 7Ca).…”
