{"product_id":"cscshpvmc","title":"High Pore Volume Mesoporous Carbon (UVMC11) for Supercapacitor and Catalyst Support, 5 g\/bottle, CSCSHPVMC","description":"\u003cp\u003eHigh Pore Volume Mesoporous Carbon (HPVMC) is a critical class of material for next-generation energy storage, particularly as a scaffold for loading pseudocapacitive or electrocatalytic \"guests.\" When the pore volume exceeds 1.5-2.0 cm3\/g, the carbon transitions from a simple surface-area provider to a high-capacity \"host\" that prevents guest materials from clumping or clogging.\u003c\/p\u003e\n\u003cp\u003eIn supercapacitors, \"High Surface Area\" (SSA) is often the focus, but Pore Volume is the metric that dictates how the device handles high power and mass loading: (1) \u003cstrong\u003eIon Reservoirs\u003c\/strong\u003e: High pore volume allows the material to act as an \"electrolyte tank.\" This ensures that even during rapid discharge (high power), there is a local supply of ions ready to form the double layer, preventing \"ion depletion\" within the electrode. (2) \u003cstrong\u003eLoading Capacity\u003c\/strong\u003e: If you are adding a pseudocapacitive catalyst (like MnO2, Ni(OH)2, or conductive polymers), high pore volume is required to hold these heavy materials without sealing the pores. A low-volume carbon will become \"blinded\" once the catalyst is added, leading to a massive drop in ion accessibility. (3) \u003cstrong\u003eMassive Triple-Phase Boundary\u003c\/strong\u003e: In gas-evolving or gas-consuming reactions, the high void space allows for simultaneous transport of electrons (through the carbon), ions (through the electrolyte), and gas bubbles (out through the macroporous\/mesoporous channels).\u003c\/p\u003e\n\u003cp\u003eWhen used to support metal oxides or noble metals (like the IrRuOx or AgNPs discussed earlier), HPVMC provides several structural benefits: (1) \u003cstrong\u003eNano-confinement\u003c\/strong\u003e: Particles are trapped in individual mesopores, which prevents sintering (particles clumping together) over time. (2) \u003cstrong\u003eConductive Scaffold\u003c\/strong\u003e: It provides a 3D network of sp2 hybridized carbon and enhances the performance of semi-conductive oxides like MnO2.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 236.275px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 41.175px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 41.175px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 41.175px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCSHPVMC (C-SCS-HPVMC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.9px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 22.9px;\"\u003e\u003cem\u003eSpecific Surface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 22.9px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~1200 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 35.6px;\"\u003e\u003cem\u003ePore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 35.6px;\"\u003e\n\u003cp\u003e~1.5 cm3\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 35.6px;\"\u003e\u003cem\u003eMesopore Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 35.6px;\"\u003e\n\u003cp\u003e2-8 um (average pore size is ~5 um)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 35.6px;\"\u003e\u003cem\u003eTap Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 35.6px;\"\u003e\n\u003cp\u003e0.4 g\/cm3\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 19.6px;\"\u003e5 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 high pore volume mesoporous carbon 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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0013468604011454\"\u003eA.
