{"product_id":"cefceruc","title":"Ruthenium\/Carbon (Ru\/C, Premetek) as Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCERuC","description":"\u003cp\u003eRuthenium on Carbon (Ru\/C) is a specialized catalyst used primarily for its performance in alkaline environments and its ability to handle \"dirty\" fuels. While Platinum (Pt\/C) is more active in acidic conditions, Ru\/C is emerging as a top-tier candidate for alkaline systems because it is significantly cheaper and, in some cases, more active than platinum.\u003c\/p\u003e\n\u003cp\u003eIn fuel cells, Ru\/C is predominantly an anode material, though it is usually alloyed with platinum to create the standard Pt-Ru\/C used in methanol fuel cells. (1) \u003cstrong\u003eAlkaline Performance (HOR)\u003c\/strong\u003e: Recent research has shown that in Anion Exchange Membrane Fuel Cells (AEMFCs), Ru\/C can exhibit higher mass activity for the Hydrogen Oxidation Reaction (HOR) than Pt\/C. It provides a more favorable hydrogen binding energy in alkaline media, making it a viable lower-cost alternative to platinum. (2) \u003cstrong\u003eCO Tolerance \u0026amp; Bifunctional Mechanism\u003c\/strong\u003e: Like its alloyed counterpart, pure Ru\/C has a natural ability to \"clean\" its own surface. It attracts water molecules to form hydroxyl (–OH) groups at low voltages, which then oxidize carbon monoxide (CO) into CO2. This prevents the catalyst from being \"poisoned\" by impurities in reformed hydrogen. (3) \u003cstrong\u003eDirect Alcohol Fuel Cells\u003c\/strong\u003e: Ru\/C is highly effective at facilitating the initial steps of alcohol oxidation. However, for complete oxidation, it is almost always paired with Pt (as Pt-Ru) to ensure the final conversion of intermediates to CO2.\u003c\/p\u003e\n\u003cp\u003eIn water electrolysis, Ru\/C is a high-performance cathode material, particularly in alkaline systems. (1)\u003cstrong\u003e Hydrogen Evolution Reaction (HER)\u003c\/strong\u003e: In alkaline electrolytes, Ru\/C is a \"benchmark\" material. It often demonstrates lower overpotentials (higher efficiency) than Pt\/C for producing hydrogen gas. (2) \u003cstrong\u003eCost Efficiency\u003c\/strong\u003e: Because Ruthenium is much cheaper than Platinum or Iridium, using Ru\/C at the cathode of an alkaline electrolyzer significantly reduces the capital cost of the system. (3) \u003cstrong\u003eAvoidance at the Anode\u003c\/strong\u003e: Pure Ru\/C is not suitable for the anode (OER) of a PEM electrolyzer. In acidic, high-voltage conditions, the carbon support would corrode, and the metallic Ruthenium would dissolve or over-oxidize into volatile RuO4. For the anode, RuO2 (ruthenium oxide) on a ceramic support is used instead.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 129.28%; height: 340.975px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 24.965%;
