{"product_id":"cco2rrne","title":"Nanoparticle Electrocatalysts (eg: Ag NPs, Sn NPs, Cu NPs) for CO2 Electroreduction (CO2RR), 1 g\/bottle, CCO2RRNE","description":"\u003cp\u003eElectrocatalyst powders for CO2 Electroreduction (CO2RR) are specifically engineered to convert carbon dioxide into high-value chemicals like Ethylene (C2H4), Ethanol (C2H5OH), Carbon Monoxide (CO), or Formic Acid (HCOOH).\u003c\/p\u003e\n\u003cp\u003eSilver nanoparticles (AgNPs) are among the most efficient catalysts for the electrochemical reduction of CO2 to Carbon Monoxide (CO). Silver is effective because it binds the *COOH intermediate just strongly enough to facilitate the reaction, but binds the final *CO weakly, allowing it to desorb quickly and free up the active site.\u003c\/p\u003e\n\u003cp\u003eTin (Sn) nanoparticles are the primary catalyst for the production of Formate (HCOO-) or Formic Acid (HCOOH). Tin operates via a 2-electron transfer. Its high selectivity for formate is driven by its interaction with the OCHO* intermediate: (1) \u003cstrong\u003eWeak CO Affinity\u003c\/strong\u003e: Tin has a very low binding affinity for CO, which prevents the catalyst from being \"poisoned\" and suppresses the pathway toward hydrocarbons. (2) \u003cstrong\u003eThe Oxide Interface\u003c\/strong\u003e: Recent operando studies confirm that the most active phase is often a metastable Sn\/SnOx interface. The presence of surface oxides and oxygen vacancies lowers the energy barrier for CO2 activation while simultaneously suppressing the competing Hydrogen Evolution Reaction (HER).\u003c\/p\u003e\n\u003cp\u003eCopper is the only metal capable of producing multi-carbon (C2+) chemicals such as Ethylene (C2H4), Ethanol (C2H5OH), and Propanol at significant rates. (1)\u003cstrong\u003e For Ethylene (C2H4)\u003c\/strong\u003e: Favored by high local pH and low water availability, which can be realized by using hydrophobic coatings (like specific alkyl chains or PTFE) on CuNPs enriches the local concentration of CO2 and *CO intermediates. This promotes the symmetric coupling of two *CO molecules, leading to ethylene. (2) \u003cstrong\u003eFor Ethanol (C2H5OH)\u003c\/strong\u003e: Favored by hydrogenation-rich environments., which can be achieved by introducing \"proton-donating\" groups or superhydrophobic surfaces that weaken hydrogen bonding can steer the reaction. For example, Cu nanofibers coated with conductive polypyrrole using PVP templates have achieved a remarkable 66.5% FE for ethanol by promoting the asymmetric coupling of *CO and *CHO.\u003c\/p\u003e\n\u003ctable style=\"width: 132.489%; height: 225.337px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 27.9153%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 24.5095%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCO2RRNEAg\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.2482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCO2RRNESn\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 22.7581%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCO2RRNECu\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: 27.9153%; height: 35.6px;\"\u003e\u003cem\u003eActive Catalyst\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 24.5095%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eAg NPs\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.2482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eSn NPs\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 22.7581%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCu NPs\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: 27.9153%; height: 35.6px;\"\u003e\u003cem\u003eParticle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 24.5095%; height: 35.6px;\"\u003e\n\u003cp\u003e50-80 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.2482%; height: 35.6px;\"\u003e\n\u003cp\u003e50-80 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 22.7581%; height: 35.6px;\"\u003e\n\u003cp\u003e30-50 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 27.9153%; height: 35.6px;\"\u003e\u003cem\u003eTarget Products\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 24.5095%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCO\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.2482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eFormate (salt)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 22.7581%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC2+\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 41.875px;\"\u003e\n\u003ctd style=\"width: 27.9153%; height: 41.875px;\"\u003e\u003cem\u003eTesting Performance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 24.5095%; height: 41.875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCO2RRNE_01_160x160.png?v=1771179236\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 24.2482%; height: 41.875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCO2RRNE_02_160x160.png?v=1771179236\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 22.7581%; height: 41.875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCO2RRNE_03_160x160.png?v=1771179236\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21.4625px;\"\u003e\n\u003ctd style=\"width: 27.9153%; height: 21.4625px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 24.5095%; height: 21.4625px;\"\u003e1.0 g\/bottle\u003c\/td\u003e\n\u003ctd style=\"width: 24.2482%; height: 21.4625px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 22.7581%; height: 21.4625px;\"\u003e\u003cbr\u003e\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 nanoparticle electrocatalyst 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:\/\/pubs.acs.org\/doi\/full\/10.1021\/acscatal.3c03446\"\u003eX.
