{"product_id":"cscsmcns","title":"Mesoporous Carbon Nanosphere (CN05) for Supercapacitor and Catalyst Support, 5 g\/bottle, CSCSMCNS","description":"\u003cp\u003eMesoporous carbon nanospheres (MCNs) represent a specialized morphology that combines the high surface area of mesoporous carbon with the unique transport advantages of a spherical geometry. As a catalyst support for supercapacitors, they solve several \"packaging\" and \"transport\" problems that plague traditional bulk carbon or carbon blacks.\u003c\/p\u003e\n\u003cp\u003eThe spherical shape provides several physical advantages over irregular carbon flakes: (1) \u003cstrong\u003eInterstitial Macropores\u003c\/strong\u003e: When nanospheres are packed into an electrode, they naturally create a network of \"voids\" between the spheres. This hierarchical structure (mesoporous internal structure + macroporous external voids) ensures that electrolyte ions can flood the entire electrode thickness almost instantly. (2) \u003cstrong\u003eShort Diffusion Paths\u003c\/strong\u003e: In a bulk carbon particle, ions may have to travel deep into a \"dead-end\" pore. In a nanosphere (typically 100–500 nm in diameter), the maximum distance an ion must travel to reach an active site is limited to the radius of the sphere, enabling ultra-high power density. (3) \u003cstrong\u003eStructural Integrity\u003c\/strong\u003e: Spheres distribute mechanical stress more evenly than irregular particles. During the charge\/discharge cycles of a pseudocapacitive guest (which often involves swelling), the spherical matrix is less likely to crack or \"pulverize.\"\u003c\/p\u003e\n\u003cp\u003eWhen used to host \"guests\" such as MnO2, V2O5, or Ni-Fe hydroxides, MCNs act as a high-performance scaffold: (1) \u003cstrong\u003eUniform Catalyst Loading\u003c\/strong\u003e: The radial pore structure of MCNs (often \"dendritic\" or \"sunflower-like\") allows the catalyst to be deposited uniformly from the center to the surface. This prevents the \"surface crust\" problem where the catalyst only coats the outside of the carbon, blocking the internal pores. (2) \u003cstrong\u003eHigh Conductive Contact\u003c\/strong\u003e: Every nanoparticle of the catalyst is in direct contact with the conductive carbon walls of the sphere. This is critical for semi-conductive oxides, as it ensures fast electron transfer to the current collector. (3) \u003cstrong\u003eNano-Confinement\u003c\/strong\u003e: The mesopores (2–10 um) physically prevent the catalyst particles from growing too large (Ostwald ripening). Smaller catalyst particles mean more active surface area and higher specific capacitance.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 174.175px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 43.575px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 43.575px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 43.575px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCSMCNS (C-SCS-MCNS)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 24.3125px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 24.3125px;\"\u003e\u003cem\u003eSpecific Surface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 24.3125px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e1280-1400 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 10px;\"\u003e\u003cem\u003ePore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 10px;\"\u003e\n\u003cp\u003e1.8-3.0 cm3\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.2158%;\"\u003e\u003cem\u003ePore Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%;\"\u003e\n\u003cp\u003e2-6 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 37.7px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 37.7px;\"\u003e\u003cem\u003eNanosphere Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 37.7px;\"\u003e\n\u003cp\u003e20-35 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20.8875px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 20.8875px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 20.8875px;\"\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 mesoporous carbon nanosphere 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\/ie403950t\"\u003eY.
