{"product_id":"cemabenifeldh","title":"Nickel-Iron Layered Double Hydroxide (NiFe-LDH) as Electrocatalysts for Electrolyzer and Metal-Air Battery, 1 g\/bottle, CEMABENiFeLDH","description":"\u003cp\u003eNickel-Iron Layered Double Hydroxide (NiFe-LDH) is widely regarded as the most active non-precious metal electrocatalyst for alkaline energy applications. Its unique 2D \"brucite-like\" host layers provide a massive surface area and a tunable electronic environment that is perfectly optimized for oxygen and nitrogen-based chemistry.\u003c\/p\u003e\n\u003cp\u003eIn Anion Exchange Membrane (AEM) and Alkaline Water Electrolyzers (AWE), NiFe-LDH is the undisputed benchmark for the Oxygen Evolution Reaction (OER) at the anode. (1) \u003cstrong\u003eLow Overpotential\u003c\/strong\u003e: Commercial-grade NiFe-LDH can drive significant current densities at remarkably low overpotentials, typically requiring only 230–260 mV to reach 10 mA\/cm2 in 1.0 M KOH. (2) \u003cstrong\u003eThe Ni-Fe Synergy\u003c\/strong\u003e: The interaction between Ni and Fe centers optimizes the binding energy of O* and OH* intermediates. While Nickel provides the conductive framework, Iron is often cited as the true \"active site\" that triggers the 4-electron water-splitting process. (3) \u003cstrong\u003eSeawater Electrolysis\u003c\/strong\u003e: NiFe-LDH is uniquely resistant to chloride corrosion. It is a top candidate for Direct Seawater Electrolysis, where it can split water into hydrogen and oxygen without generating toxic chlorine gas.\u003c\/p\u003e\n\u003cp\u003eA growing application for NiFe-LDH is the Urea Oxidation Reaction (UOR), which is used for both wastewater treatment and \"urea-assisted\" hydrogen production. (1) \u003cstrong\u003eLower Voltage Requirements\u003c\/strong\u003e: Splitting water theoretically requires 1.23 V. However, oxidizing urea only requires 0.37 V. By replacing the water-splitting anode with a NiFe-LDH urea-oxidation anode, the total energy consumption of the electrolyzer can be reduced by over 15–20%. (2) \u003cstrong\u003eEnvironmental Remediation\u003c\/strong\u003e: NiFe-LDH nanosheets are used to degrade urea in industrial and agricultural runoff, converting a pollutant into nitrogen gas and water while simultaneously generating clean hydrogen at the cathode.\u003c\/p\u003e\n\u003ctable style=\"width: 101.819%; height: 486px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 53.3875px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 53.3875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 53.3875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEABNiFeLDH\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.3125px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 47.3125px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 47.3125px;\"\u003e\n\u003cp\u003eLight Yellow to Brownish-Green\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 30.2548%; height: 10px;\"\u003e\u003cem\u003eSpecific Surface Area (BET):\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~120 m2\/g\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\u003eTesting Performance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eOverpotential for water oxidation: 230–280 mV at 10 mA\/cm2\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTafel Slope: ~30–50 mV\/dec\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.2548%;\"\u003e\u003cem\u003eElectrolyte Stability\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%;\"\u003e\n\u003cp\u003e\u003cspan\u003eHighly stable in alkaline conditions (pH \u0026gt; 13), but will dissolve in acidic environments (pH \u0026lt; 5)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.2548%;\"\u003e\u003cem\u003eCatalyst Ink Preparation\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%;\"\u003e\n\u003cp\u003e\u003cspan\u003e10 mg NiFe-LDH + 50 um Nafion (5 wt%) + 4.95 mL DI H2O + 5 mL ethanol for 5 min ultrasonication to get well-dispersed ink\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.2548%;\"\u003e\u003cem\u003eCatalyst Electrode Preparation \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3567%;\"\u003e\n\u003cp\u003e\u003cspan\u003e(1) The substrate was ultrasonically cleaned with acetone, ethanol, and DI H2O for 10 min and dry it at 80°C.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(2) Place the ink into the spray gun for uniform coating on the substrate.
