{"product_id":"caeeanifeo","title":"Amorphous Nickel-Iron Oxide (NiFeOx) as Electrocatalysts for Alkaline Electrolyzer, 1 g\/bottle, CAEEANiFeO","description":"\u003cp\u003eNickel-Iron Oxides (NiFeOx) are among the most powerful and cost-effective electrocatalysts for alkaline environments. While they are closely related to NiFe-LDH (Layered Double Hydroxides), the \"Ox\" notation typically refers to the bulk oxide or amorphous mixed-oxide forms, which often serve as the stable \"pre-catalyst\" for high-performance industrial applications.\u003c\/p\u003e\n\u003cp\u003eThe primary application of NiFeOx is as the anode catalyst for the Oxygen Evolution Reaction (OER) in alkaline water electrolysis. It is currently the industry’s best non-precious alternative to Iridium Oxide (IrO2). (1) \u003cstrong\u003eAnion Exchange Membrane (AEM) Electrolyzers\u003c\/strong\u003e: NiFeOx is the \"gold standard\" for AEM systems. It allows these electrolyzers to operate without any Platinum Group Metals (PGMs), drastically reducing stack costs while maintaining current densities of 1.0–3.0 A\/cm². (2) \u003cstrong\u003eAmorphous Advantage\u003c\/strong\u003e: Amorphous NiFeOx (often synthesized via sol-gel or electrodeposition) typically outperforms crystalline versions. The disordered structure provides more \"bridge\" and \"edge\" sites where Fe atoms can exert their maximum synergistic effect on Nickel. (3) \u003cstrong\u003eSurface Reconstruction\u003c\/strong\u003e: During operation, the surface of NiFeOx naturally transforms into NiFeOOH (oxyhydroxide). This \"in-situ\" formed layer is the true active phase that facilitates the 4-electron transfer required to release oxygen.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 115.014%; height: 338px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 29.5226%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e CAEEANiFeOP\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAEEANiFeOC\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAEEANiFeOCKB\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: 29.5226%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 35.6px;\"\u003e\n\u003cp\u003eDark brown powder\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003eBlack powder\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003eBlack powder\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 29.5226%;\"\u003e\u003cem\u003eComponents\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%;\"\u003e\n\u003cp\u003ePristine NiFeOx\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003e50 wt% NiFeOx on Vulcan XC-72\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003e50 wt% NiFeOx on Ketjen Black\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 29.5226%; height: 10px;\"\u003e\u003cem\u003eAverage Particle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 10px;\"\u003e\n\u003cp\u003e30-50 nm, nearly spherical\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003e-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003e-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 29.5226%; height: 35.6px;\"\u003e\u003cem\u003eBulk Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 35.6px;\"\u003e\n\u003cp\u003e0.87-0.95 g\/cm3\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003e-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003e-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 29.5226%; height: 35.6px;\"\u003e\u003cem\u003eTrue Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 35.6px;\"\u003e\n\u003cp\u003e5.368 g\/cm3\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003e-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003e-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 29.5226%; height: 35.6px;\"\u003e\u003cem\u003eSpecific Surface Area (BET):\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~150 m2\/g\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e\n\u003cp\u003e\u003cspan\u003e~180 m2\/g\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e\n\u003cp\u003e\u003cspan\u003e~220 m2\/g\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 43.85px;\"\u003e\n\u003ctd style=\"width: 29.5226%; height: 43.85px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 26.3985%; height: 43.85px;\"\u003e1.0 g\/bottle\u003c\/td\u003e\n\u003ctd style=\"width: 24.0555%;\"\u003e1.0 g\/bottle\u003c\/td\u003e\n\u003ctd style=\"width: 19.2131%;\"\u003e1.0 g\/bottle\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 amorphous NiFeOx powder 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.
