{"product_id":"cscsnsmc","title":"N,S-Doped Mesoporous Carbon (NSDC02, 600 m2\/g) for Supercapacitor and Catalyst Support, 2 g\/bottle, CSCSNSMC","description":"\u003cp\u003eIn electrochemical engineering, N,S-doped mesoporous carbon (NS-MC) represents the peak of heteroatom engineering for carbon supports. By simultaneously doping Nitrogen (N) and Sulfur (S), you move beyond the benefits of N-doping alone to leverage a synergistic \"spin-charge\" effect that significantly boosts both supercapacitor and electrocatalyst performance.\u003c\/p\u003e\n\u003cp\u003eWhile Nitrogen provides basic pseudocapacitance and conductivity, adding Sulfur introduces unique structural and electronic advantages: (1) \u003cstrong\u003eAsymmetric Spin Density\u003c\/strong\u003e: Nitrogen (electronegativity 3.04) and Sulfur (2.58) differ from Carbon (2.55). This creates a \"tug-of-war\" for electrons, resulting in highly polarized carbon sites. These sites are exceptionally active for Oxygen Reduction (ORR) and Oxygen Evolution (OER) reactions. (2) \u003cstrong\u003eExpanded Lattice (Structural Strain)\u003c\/strong\u003e: The Sulfur atom is significantly larger than Carbon or Nitrogen. Incorporating S into the carbon rings causes a \"bulge\" or distortion, creating physical defects that act as additional active sites and allow for faster ion diffusion. (3) \u003cstrong\u003eEnhanced Pseudocapacitance\u003c\/strong\u003e: Sulfur atoms in the form of Thiophene-S or Sulfone\/Sulfoxide groups provide secondary redox reactions that complement the pyridinic-N reactions, pushing specific capacitance to new heights.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 224.037px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 48.5875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 48.5875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 48.5875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCSNSMC (C-SCS-NSMC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 44.375px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 44.375px;\"\u003e\u003cem\u003eSpecific Capacitance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 44.375px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e340-450 F\/g (aqueous system)\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.2875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 27.2875px;\"\u003e\u003cem\u003eSurface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 27.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~600 m2\/g\u003c\/div\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\u003ePore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e2.3-3.0 g\/cm3   \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003ePore Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e1-7 nm (mesopore portion is \u0026gt;90%)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 48.5875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 48.5875px;\"\u003e\u003cem\u003eDoping Content \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 48.5875px;\"\u003e\n\u003cp\u003eN content: ~1.0 wt%\u003c\/p\u003e\n\u003cp\u003eS content: 0.8-1.0 wt%\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;\"\u003e2 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 N,S-doped 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:\/\/link.springer.com\/article\/10.1007\/s10008-022-05145-7\"\u003eY.
