{"product_id":"cefcepptc","title":"Platinum\/Carbon (Pt\/C, Premetek) Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCEPPtC","description":"\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003ePlatinum on Carbon (Pt\/C) is the industry-standard electrocatalyst for low-temperature electrochemical devices. It consists of highly dispersed platinum nanoparticles (typically 1–5 nm) anchored to a high-surface-area carbon support (like Vulcan XC-72). Premetek offers a wide variety of Platinum on Carbon (Pt\/C) electrocatalysts specifically designed for use in proton exchange membrane fuel cells (PEMFC) and electrolyzers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eIn a Proton Exchange Membrane Fuel Cell (PEMFC), Pt\/C is used at both electrodes to convert chemical energy into electricity. (1) \u003cstrong\u003eAnode (Hydrogen Oxidation Reaction - HOR)\u003c\/strong\u003e: Platinum is exceptionally efficient at breaking the H-H bond. Because this reaction is naturally fast, anode platinum loading is typically very low (around 0.05 mg\/cm²). (2) \u003cstrong\u003eCathode (Oxygen Reduction Reaction - ORR)\u003c\/strong\u003e: This is the \"bottleneck\" of fuel cell performance. Platinum facilitates the 4-electron reduction of O2 to H2O. This reaction is kinetically sluggish, requiring much higher Pt loading (around 0.3–0.4 mg\/cm²) to reach target power densities. (3) \u003cstrong\u003eChallenges\u003c\/strong\u003e: The cathode environment is highly corrosive (high voltage and acidic), leading to Ostwald ripening (Pt particles merging) and carbon support corrosion over time.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eIn a PEM Water Electrolyzer (PEMWE), Pt\/C is primarily used on only one side. (1) \u003cstrong\u003eCathode (Hydrogen Evolution Reaction - HER)\u003c\/strong\u003e: Pt\/C is the \"gold standard\" for the HER. It provides the lowest overpotential (energy penalty) for combining protons (H+) and electrons to form H2 gas. (2) \u003cstrong\u003eAnode (Oxygen Evolution Reaction - OER)\u003c\/strong\u003e: Pt\/C is generally NOT used here. The high oxidative potentials at the electrolyzer anode (often \u0026gt;1.4V) would cause the carbon support to burn away (oxidize to CO2) almost instantly. Instead, noble metal oxides like Iridium Oxide (IrO2) or Ruthenium Oxide (RuO2) on non-carbon supports are used.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 336px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEFCEPPtC (C-EFC-EPPtC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 71.2px;\"\u003e\u003cem\u003eElectrocatalyst Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 71.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eHighly dispersed platinum nanoparticles\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eVulcan XC-72 or Ketjen Black\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 29.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 29.6px;\"\u003e\u003cem\u003ePlatinum Content\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 29.6px;\"\u003e5 wt%, 10 wt%, 20 wt%, 40 wt%, and 60 wt%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 37.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 37.6px;\"\u003e\u003cem\u003eMetal Surface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 37.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~200 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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eCatalyst BET Surface Area:\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~230 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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eMetal Crystallite Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~1.0 nm\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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eCatalyst granule size D(100)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e≤ 75 µm\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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eImpurities \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e≤ 500 ppm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e0.5 g\/bottle\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 Pt\/C 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\/abs\/10.1021\/acsami.4c10430\"\u003eV.
