{"product_id":"cco2rrhaeid","title":"Hydrophobic Anion Exchange Ionomer Dispersion (5 wt%) for CO2 Electroreduction (CO2RR), 10 mL\/bottle, CCO2RRHAEID","description":"\u003cp\u003eThe CCO2RRHAED is a high-performance anion exchange ionomer (AEI) that is specifically famous for its use in CO2 electrolyzers (converting CO2 to CO or formic acid, where it significantly outperforms many other ionomers by suppressing the competing Hydrogen Evolution Reaction (HER).\u003c\/p\u003e\n\u003cp\u003eIt is based on imidazolium-functionalized styrene chemistry. (1) \u003cstrong\u003eBackbone\u003c\/strong\u003e: Styrenic (polystyrene-based). (2) \u003cstrong\u003eFunctional Group\u003c\/strong\u003e: 1,2,4,5-tetramethylimidazolium. (3) \u003cstrong\u003eShipping Form\u003c\/strong\u003e: It is almost always shipped in the Chloride (Cl-) form to ensure stability.\u003c\/p\u003e\n\u003cp\u003eIt has following features: (1) \u003cstrong\u003eCO2 Affinity\u003c\/strong\u003e: The imidazolium groups have a natural affinity for CO2 molecules. This creates a \"locally concentrated\" CO2 environment at the catalyst surface, which is why it is the \"gold standard\" for CO2 reduction research. (2) \u003cstrong\u003eWater Suppression\u003c\/strong\u003e: It is engineered to be relatively hydrophobic compared to some fuel cell ionomers. This helps prevent water from reaching the catalyst sites, which minimizes unwanted hydrogen production (HER) during CO2 electrolysis. (3) \u003cstrong\u003eHigh Conductivity\u003c\/strong\u003e: Once converted to the OH- form, it maintains excellent ionic transport, allowing for high current densities (often \u0026gt;500 mA\/cm2 in optimized cells).\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 389.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.9456%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8746%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCO2RRHAEID (C-CO2RR-HAEID)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 129.6px;\"\u003e\n\u003ctd style=\"width: 35.9456%; height: 129.6px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8746%; height: 129.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCO2RRAEDSXA9_02_160x160.png?v=1771438637\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.9456%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8746%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eTransparent Liquid \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: 35.9456%; height: 35.6px;\"\u003e\u003cem\u003eSolvent\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8746%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e5 wt% in\u003cstrong\u003e ethanol\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 35.9456%; height: 39.2px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 63.8746%; height: 39.2px;\"\u003e10 mL\/bottle (the solid powder form with 0.4 g\/bottle also can be supplied upon request)\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 anion exchange dispersion in a dry place (glovebox is the best option). \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\/abs\/10.1002\/cssc.202201687\"\u003eM .Chang, et al.
