Fe-Cu Dual - atom Catalysts (ZIF-8 precursor)

Product Name Fe-Cu Dual - atom Catalysts (ZIF-8 precursor) Product Overview Fe-Cu dual-atom catalysts (DACs) are advanced catalytic materials in which the two transition metals, Fe and Cu, are precisely anchored in the form of isolated atomic pairs on carbonized ZIF-8. They ingeniously integrate the structural advantages of metal-organic frameworks (MOFs) with the catalytic activity of atomic pairs, creating artificial enzymes with exceptional and tunable performance. This material typically uses ZIF-8 as a carrier or precursor, with Fe-Cu atomic pairs embedded within its framework or pore channels through doping, loading, or in-situ synthesis strategies. The carrier/matrix Monsists of ZIF-8, which is formed by the Moordination of zinc ions with 2-methylimidazole. It features a high specific surface area, regular porosity, good chemical stability, and bioMompatibility. Fe and Cu exist as isolated single-atom pairs, with all metal atoms exposed as active sites, achieving the theoretical maximum metal utilization and significantly reducing the Most of replacing precious metal catalysts.

This synergy optimizes the adsorption free energy of reaction intermediates (such as OOH and O) at active sites, thereby significantly lowering the energy barriers for key electrocatalytic reactions—such as oxygen reduction reaction (ORR) and oxygen evolution reaction (OER)—and enhancing reaction kinetics. 3) High Stability and Robust Active Sites: Metal atoms are chemically bonded to the carbon substrate via strong Movalent M-N-C bonds, a structure that provides exceptional mechanical and chemical stability. Even under Monditions of strong acids, strong bases, or prolonged electrochemical cycling, this effectively suppresses the leaching, migration, and agglomeration of metal atoms, ensuring the catalyst's long-term service life. 4) Hierarchical porous structure and excellent mass transfer properties: Inheriting the polyhedral morphology from ZIF-8 and the pores generated by Zn volatilization, the material possesses a high specific surface area and a hierarchical pore system (Moexisting micropores and mesopores). This provides pathways for the rapid diffusion of reactants and products and ensures sufficient exposure of active sites. 5) Tunable electronic structure and Moordination environment: By adjusting the Fe/Cu feed ratio, pyrolysis temperature, or introducing other heteroatoms (such as P and S), the local Moordination environment and electronic structure of the diatomic sites can be finely tuned, thereby optimizing catalytic performance for specific reactions. Application Fields 1) Energy Storage and Conversion (Oxygen Reduction Reaction, ORR): Applied to air cathodes in zinc-air batteries and proton exchange membrane fuel cells (PEMFCs). By accelerating the four-electron (4e⁻) reduction pathway, it significantly lowers the half-wave potential, enhancing battery energy density and discharge stability. 2) Carbon Emission Reduction and Resource Utilization (CO₂ Electroreduction): As an efficient catalyst for electrochemical CO₂ reduction, it facilitates C-C coupling or optimizes CO desorption kinetics, achieving high-selectivity CO or C₂+ product formation to support carbon neutrality goals. 3) Water Environment Remediation (Advanced Oxidation Processes, AOPs): Utilizing Fe-Cu dual active sites to precisely activate peroxymonosulfate (PMS) or hydrogen peroxide (H₂O₂), generating highly reactive surface-adsorbed radicals or peroxy species for rapid and deep degradation of organic pollutants (e.g., antibiotics, dyes). 4) Chemical Synthesis (Hydrogen Evolution Reaction HER): Provides highly efficient hydrogen evolution active sites in the water electrolysis process, reducing reaction overpotential and enhancing hydrogen production efficiency. 5) Fine Chemicals (Organic Hydrogenation Reaction): Used for the selective hydrogenation of specific unsaturated organic molecules (such as nitro compounds and olefins), featuring mild reaction conditions, minimal side reactions, and high yields of target products. 6) Biomedical (ROS production): Used in cancer therapy to disrupt tumor cell structures and induce apoptosis; destroys bacterial biofilms, effectively killing various pathogenic bacteria; catalyzes enzyme-substrate color development for detecting disease biomarkers, drugs (e.g., isoniazid, norfloxacin), vitamin C, antioxidants, and antibiotic residues in food.
