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-Mo 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 Mo 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\/Mo 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 conversion and storage: In biomimetic nitrogenase, the \"FeMo cofactor\" features an iron site responsible for adsorbing and activating N₂ molecules, while the molybdenum site provides active hydrogen to accelerate proton transfer; this synergistic effect significantly enhances ammonia yield and Faradaic efficiency; Fe-Mo Dual - atom catalysts can simultaneously catalyze the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER), with performance even surpassing that of commercial Pt\/C and RuO₂ catalysts. In zinc-air batteries, FeMo\/NC-based cells can operate stably for over 200 hours without significant performance degradation and demonstrate equally outstanding performance in flexible batteries. 2) Environmental Remediation: Fe-Mo Dual - atom catalysts can efficiently activate persulfates (PMS) to rapidly degrade pollutants such as ciprofloxacin and phenol, featuring short reaction times and high removal rates; Some catalysts can simultaneously convert highly toxic nitrite intermediates into nitrogen gas, achieving complete removal of pollutants; they exhibit excellent pH adaptability, ultra-low metal leaching rates, and high stability. 3) Biomedical and Sensing Fields: Their nanoenzyme activity generates large amounts of reactive oxygen species (ROS), effectively killing tumor cells. Fe-Mo catalysts have become a key cutting-edge platform for cancer treatment, capable of integrating catalytic, photothermal, sonodynamic, and even immunotherapy approaches to achieve precise and highly efficient synergistic treatment; furthermore, leveraging their strong peroxidase-like activity, they can be used to construct highly sensitive detection platforms for substances such as phenolic pollutants, hydrogen peroxide, and uric acid, with detection limits as low as the nanomolar range.\u003c\/p\u003e","brand":"xfnano","offers":[{"title":"50mg D:~200 nm 110475 \/ Store at room temperature in a dry, dark and sealed place \/ 180days","offer_id":57280535626106,"sku":"110475","price":156.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0907\/3606\/6938\/files\/1_27871cef-ce01-415a-9a0e-d29d5e516d17.png?v=1780024497","url":"https:\/\/chinanano.com\/fr\/products\/fe-mo-dual-atom-catalysts-zif-8-precursor","provider":"xfnano","version":"1.0","type":"link"}
