{"product_id":"cefceagc","title":"Silver\/Carbon (Ag\/C, Premetek) as Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCEAgC","description":"\u003cp\u003eSilver on Carbon (Ag\/C) is a specialized electrocatalyst that has gained significant traction as a high-performance, lower-cost alternative to Platinum in specific alkaline environments. While it performs poorly in acidic PEM systems, it is a leading contender for Alkaline Exchange Membrane (AEM) technologies and CO2 electrolysis.\u003c\/p\u003e\n\u003cp\u003eIn alkaline media, silver becomes a highly effective catalyst for the Oxygen Reduction Reaction (ORR) at the cathode. (1) \u003cstrong\u003eCost-Effective Cathode\u003c\/strong\u003e: Silver is approximately 1\/50th the price of Platinum. In alkaline fuel cells, Ag\/C can achieve ORR activity that approaches or even matches Pt\/C, making it the primary strategy for reducing the \"stack cost\" of fuel cells. (2) \u003cstrong\u003e4-Electron Pathway\u003c\/strong\u003e: While many non-Pt catalysts produce harmful peroxide (H2O2), high-quality Ag\/C nanoparticles favor the efficient 4-electron pathway, converting oxygen directly into hydroxide ions (OH-). (3) \u003cstrong\u003eTolerance to Impurities\u003c\/strong\u003e: Ag\/C is more resistant to poisoning from certain fuel impurities compared to Platinum, which can be critical when using less-than-pure hydrogen sources.\u003c\/p\u003e\n\u003cp\u003eSilver is the industry standard for the Electrochemical CO2 Reduction Reaction (CO2RR). (1) \u003cstrong\u003eSelectivity for CO\u003c\/strong\u003e: Ag\/C is exceptionally good at converting CO2 into Carbon Monoxide (CO). It offers a high Faradaic Efficiency (often \u0026gt;90%), meaning almost all the electricity used goes into creating CO rather than wasted hydrogen. (2) \u003cstrong\u003eHydrogen Suppression\u003c\/strong\u003e: Silver has a high \"overpotential\" for the Hydrogen Evolution Reaction (HER). In the context of CO2 electrolysis, this is a major advantage because it prevents hydrogen gas from diluting the desired carbon product. (3) \u003cstrong\u003eMorphology Matters\u003c\/strong\u003e: Research often focuses on \"Ag-Nanowires\" or \"Ag-Flowers\" on carbon supports to maximize the number of active edge sites, which are more reactive than the flat facets of the silver crystal.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 135.877%;
