{"product_id":"caeceanifeo","title":"Amorphous Nickel-Iron Oxide (NiFeOx) Coated Electrode for Alkaline Electrolyzer, CAECEANiFeO","description":"\u003cp\u003eIntegrating NiFeOx (Nickel-Iron Oxide) onto Nickel felt creates a high-performance anode specifically engineered for the rigorous conditions of industrial alkaline electrolyzers. While Nickel foam is common in labs, Nickel felt is the preferred substrate for commercial-scale systems due to its superior fiber density and bubble management.\u003c\/p\u003e\n\u003cp\u003eNiFeOx is an amorphous mixed-metal oxide that serves as the \"pre-catalyst\" for the Oxygen Evolution Reaction (OER). (1) \u003cstrong\u003eAmorphous Advantage\u003c\/strong\u003e: Disordered NiFeOx typically outperforms crystalline versions because it possesses a higher density of coordinatively unsaturated sites (defects) that are more chemically active. (2) \u003cstrong\u003eIn-situ Reconstruction\u003c\/strong\u003e: Once voltage is applied in KOH, the surface of the NiFeOx naturally transforms into NiFeOOH (oxyhydroxide). This nanometer-thick layer contains the true active Fe^{4+} sites.\u003c\/p\u003e\n\u003cp\u003eMetal felt (eg: Ti, Ni, SS) is a non-woven, sintered fiber network. Its physical structure provides distinct advantages over foam or mesh for high-current applications. (1) \u003cstrong\u003eMicro-Fiber Connectivity\u003c\/strong\u003e: The felt consists of micro-scale fibers (typically 20–80 um in diameter) that are sintered together. This creates a much more robust electrical network compared to the thinner struts of metal foam. (2) \u003cstrong\u003eEffective Surface Area\u003c\/strong\u003e: The dense, entangled fibers provide a massive surface area-to-volume ratio, allowing for high catalyst loading without clogging the 3D transport pathways. (3) \u003cstrong\u003eCapillary Bubble Transport\u003c\/strong\u003e: The micro-pores in the felt act as capillary channels, pulling electrolyte in and pushing oxygen bubbles out more efficiently than larger-pore foams. This minimizes \"gas shielding,\" which is the primary cause of efficiency loss at high current densities.\u003c\/p\u003e\n\u003ctable style=\"width: 101.819%; height: 382.45px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAECEANiFeO\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 55.2px;\"\u003e\u003cem\u003eElectrode Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 55.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eAmorphous NiFeOx active material sprayed on the various conductive substrates\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 55.2px;\"\u003e\u003cem\u003eBinder Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 55.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eNafion ionomer was default selected, but PiperION is also available upon request. \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 142.4px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 142.4px;\"\u003e\u003cem\u003eSubstrates\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 142.4px;\"\u003e\n\u003cp\u003e\u003cspan\u003e(1) Nickel Felt\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(2) Titanium Felt\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(3) Stainless Steel Felt\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(4) Carbon Paper\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSpecial coating (eg: Pt) and hydrophobic surface treatment (eg: PTFE) on the substrate can be additionally supplied upon request. \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 35.6px;\"\u003e\u003cem\u003eLoading Amount\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e2 mg\/cm2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 35.6px;\"\u003e\u003cem\u003eElectrode Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eL 50mm * W 50mm \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.85px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 22.85px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 22.85px;\"\u003e1 pcs\/pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the NiFeOx electrodes in a dry place.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/chemistry-europe.onlinelibrary.wiley.com\/doi\/full\/10.1002\/celc.202500081\"\u003eR.
