{"product_id":"cefceptnic","title":"Platinum-Nickel (Pt-Ni, Premetek) Alloy on Carbon Black as Electrocatalysts for Electrolyzer and Fuel Cell, 0.5 g\/bottle, CEFCEPtNiC","description":"\u003cp\u003ePlatinum-Nickel (Pt-Ni) electrocatalysts represent the \"cutting edge\" of fuel cell research. While Pt-Co is the current commercial standard (used in the Toyota Mirai), Pt-Ni has demonstrated the highest theoretical and lab-scale activity ever recorded for the Oxygen Reduction Reaction (ORR). The fascination with Pt-Ni lies in its specific crystal structures—particularly the octahedral shape—which can outperform standard Pt\/C by more than 10 times in mass activity.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eIn PEMFCs, Pt-Ni is the premier candidate for the cathode (ORR). (1) \u003cstrong\u003eThe (111) Facet Advantage\u003c\/strong\u003e: Research into Pt-Ni reached a breakthrough when it was discovered that the Pt3Ni (111) surface is exceptionally active. Octahedral nanoparticles (8-sided) exclusively expose these (111) facets, leading to \"record-breaking\" performance. (2) \u003cstrong\u003eMassive Activity Boost\u003c\/strong\u003e: Lab-scale Pt-Ni octahedral catalysts have shown ORR activities up to 90 times higher than state-of-the-art commercial Pt\/C. This allows for significantly lower platinum loading while maintaining high power output. (3) \u003cstrong\u003eElectronic Tuning\u003c\/strong\u003e: The Nickel atoms cause a lattice contraction (compressive strain) and electronic shifts (ligand effect) that prevent oxygen intermediates from \"sticking\" too tightly to the Platinum, speeding up the reaction.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn PEM electrolyzers, Pt-Ni is primarily used at the cathode (HER). (1) \u003cstrong\u003eHigh HER Activity\u003c\/strong\u003e: Pt-Ni alloys are highly efficient for the Hydrogen Evolution Reaction. Interestingly, the activity is \"potential-dependent,\" meaning the catalyst can actually restructure itself during operation to become more active. (2) \u003cstrong\u003eStability Concerns (Leaching)\u003c\/strong\u003e: The main challenge in electrolyzers is the highly acidic environment. Nickel is more prone to leaching (dissolving) than Cobalt or Iron. If Ni^2+ ions escape, they can contaminate the Nafion membrane, reducing its proton conductivity and shortening the system's life. (3) \u003cstrong\u003eSolution\u003c\/strong\u003e: Commercial-grade Pt-Ni is often \"de-alloyed\" or \"acid-etched\" during manufacturing to create a Pt-skin—a protective layer of pure platinum that cages the Ni-rich core.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%;
